I can't see a way to figure out what's going on without help from your network admins; we need some insight into why the connection is being reset on the server side, and analyzing the TCP stream on the client can't tell us that. BTW, if you think it'd help to try a live debugging session, I'm only about an hour's drive away from IJS. So to wrap this up: they managed to fix the problem themselves, and it was indeed some part of the network infrastructure; the specifics are as follows: They have a Cisco ASA 5580 running IOS 9.1(4), and they had HTTP protocol inspection turned on; the configuration was as follows: policy-map type inspect http HTTP-CONTROL parameters protocol-violation action log policy-map global_policy class inspection_default inspect http HTTP-CONTROL The ASA was closing the connections, and their logs contained one of the following two reasons: %ASA-4-415016: policy-map HTTP-CONTROL:Maximum number of unanswered HTTP requests exceeded - Resetting connection from Ext:x.x.x.x/59769 to Int:y.y.y.y/80 %ASA-4-507003: tcp flow from Ext:x.x.x.x/59769 to Int:y.y.y.y/80 terminated by inspection engine, reason - reset unconditionally. The only reasonable explanation we could come up with was that moderately low bandwidth and high latency between client and server, coupled with the fact that some of the files in the repository are rather large and take a while to transfer, caused the 1.8 client to queue up enough pipelined GET requests during checkout that the firewall decided to call quits. A 1.7 client (using serf) did not exhibit this problem, because it also sends PROPGETS, and this apparently changed the timing enough that the number of pipelined requests never exceeded the ASA's configured maximum. Apparently this is not a new problem, having been reported before: https://supportforums.cisco.com/thread/2088590 They fixed the issue by switching off HTTP protocol inspection on the ASA. Interestingly enough, this also fixed a number of intermittent issues with plain ol' Web browsing that they had on occasion, so this is not specific to Subversion (as the link above also suggests), but is rather a bug^Wserious limitation of the ASA and/or IOS. -- Brane -- Branko Čibej | Director of Subversion WANdisco // Non-Stop Data e. br...@wandisco.com

Very occasionally the checkout works but most of the time the client simply hangs while receiving the first file. It appears that the client is sending the REPORT request and receiving the response from the server. The client then pipelines 13 GET requests corresponding to the 13 files in the working copy. The server starts sending the response to the first GET and the client starts receiving it but the server never completes the response. The client hangs waiting for the server and eventually times out. If I use wireshark it shows the server sending an RST packet just before the client hangs. According to wireshark this is a Bad checksum packet. Wireshark shows the client retransmitting the GETs but there is no further server repsonse. I don't know enough to debug the problem further. I now upgraded the SVN client to 1.9.0-dev from trunk. With trunk version it's still inconsistent behaviour, but at least reproducible to a certain extent. I tried to checkout file a couple of times. Almost every time I get the following lines in error.log on the server: Unable to deliver content. [500, #0] Could not write data to filter. [500, #175002] but the first time the whole checkout finished successfully, even though the server first recorded 500 and apparently another 200 (success) on the second attempt for the same file. The client ended with success. The second time the client reported svn: E54: Error running context: Connection reset by peer (and the same happened when I ran it for the third/fourth/fifth/... time) Sometimes it works though. And it usually hangs on different files. I'm unable to reproduce the faulty behaviour if I do a checkout from the same network where the server is located, no matter what I try (upgrading SVN client doesn't help triggering the error). Philip also said that he had no problem doing a checkout with client version 1.8.5 or 1.7. With subversion client 1.8.5 I'm sometimes able to reproduce the problem from a different network, but it usually works. I tried wireshark, but I don't know what to do with the zillions of packets it shows me. I'll first try to copy the repository to another server to see if I could reproduce the problem from there. Other than that I would be grateful for any hints if there exists some painless way to debug the server. Mojca

Actually we know we haven't covered all possibilities. Had someone a while back that had mod_security setup in such a way that it was rejecting some request methods (think it was POST) without Content-Length (thus breaking chunked requests). The behavior didn't fail for the OPTION requests so our probe to try and work around transparent proxies failed. But I'm not sure what this thread would really have to do with chunked requests, since the problem seems to be pipelining which as far as I know we don't have any workarounds for. We can rule out the chunked requests by disabling it by adding this to the command line --config-option servers:global:http-chunked-requests=no and seeing if it changes anything.

When it fails it ususally hangs and eventually times-out, but occasionally it fails with Connection reset by peer. 1.8 fails like trunk, but 1.7/serf works. If we believe Wireshark then the server is sending an RST part way through the response to the first of 13 pipelined GETs. The response reponse is not chunked, it has Content-Length:8407648, but the client only receives 14480 bytes (I think that includes the headers). 1.7/serf, which works, pipelines 13 PROPFINDs as well as 13 GETs. If I force trunk to pipeline the PROPFINDs using: Index: ../src/subversion/libsvn_ra_serf/update.c === --- ../src/subversion/libsvn_ra_serf/update.c (revision 1557003) +++ ../src/subversion/libsvn_ra_serf/update.c (working copy) @@ -1630,7 +1630,7 @@ val = svn_xml_get_attr_value(inline-props, attrs); if (val (strcmp(val, true) == 0)) -ctx-add_props_included = TRUE; +ctx-add_props_included = FALSE; val = svn_xml_get_attr_value(send-all, attrs); if (val (strcmp(val, true) == 0)) @@ -1638,7 +1638,7 @@ ctx-send_all_mode = TRUE; /* All properties are included in send-all mode. */ - ctx-add_props_included = TRUE; + ctx-add_props_included = FALSE; } } else if (state == NONE strcmp(name.name, target-revision) == 0) then the checkout with trunk starts working reliably.

If you did that while Apache was running, without restarting Apache, then that explains the 'Corrupt node-revision' error as you changed the data on disk. Ah, thanks a lot for explaining that. Yes, I did dump/load the old repository into a new one because I wanted to test if it would solve the problem (on client) svn: E54: Error retrieving REPORT: Connection reset by peer (on server) [dav:error] [pid 3613] [client ip] Unable to deliver content. [500, #0] [dav:error] [pid 3613] [client ip] Could not write data to filter. [500, #175002] which it didn't. It only added a few additional problems until I restarted Apache (I'm sorry for confusing you with those), but the initial error E54/175002 is still causing problems. What you are left with is some sort of intermittent network problem. I don't know what is causing that. Is there any way to debug that? Thank you very much, Mojca

Seeking help for E000054: Error retrieving REPORT: Connection reset by peer
Hello, We have a server running Fedora which has recently been upgraded to version 20 and it's now running svn, version 1.8.5 (r1542147) I have a bunch of repositories served over http protocol with public read access and limited commit access. Shortly after the upgrade a weird behaviour has been noticed. Running svn up on the top level dir worked ok for me, but running svn co http://svn.myserver.net/myrepo/dirA fails with AdirA/subdir1 AdirA/subdir2 AdirA/subdir3 AdirA/subdir4 svn: E54: Error retrieving REPORT: Connection reset by peer The directory dirA contains one more file FILE.txt. Checking out any individual subdirN works and the browser is able to display the contents of dirA. Trying to click on FILE.txt in the browser sometimes works (it currently does) and sometimes shows an XML (like a few minutes ago, but I'm unable to get it now), saying something similar to the error I get in console***: svn: E175002: Unable to connect to a repository at URL 'svn.myserver.net/myrepo/dirA' svn: E175002: Unexpected HTTP status 500 'Internal Server Error' on '/myrepo/dirA' svn: E160004: Additional errors: svn: E160004: Corrupt node-revision '2-1.0.r137/330061' (*** To be precise: this is the error I get after upgrading the repository to the latest version of SVN, I didn't try to get to this error before upgrading.) The error.log in apache says just: [date] [dav:error] [pid 3613] [client ip:port] Unable to deliver content. [500, #0] [date] [dav:error] [pid 3613] [client ip:port] Could not write data to filter. [500, #175002] I first tried if upgrading the repository would help in any way, so I did svnadmin dump oldrepo | svnadmin load newrepo and checking the relevant revision r137 cited in the error all I see is the following (nothing unusual): --- Committed revision 136 Started new transaction, based on original revision 137 * editing path : dirA/FILE.txt ... done. * Dumped revision 137. * editing path : dirA/subdir1/somefile ... done. --- Committed revision 137 Checking out the same repository via http on the machine where the repository itself is located works fine. I'm using the same version of SVN (1.8.5) on Mac, but other svn clients on other OSes have problems as well. I tried checking the repository health with svnadmin verify /path/to/myrepo and all revisions passed except for some weird error inbetween (the file rev-prop-atomics.mutex is actually missing, but it isn't present in any other repository either): * Verifying repository metadata ... * Verifying metadata at revision 1 ... ... * Verifying metadata at revision 155 ... svnadmin: E160052: Revprop caching for '/path/to/myrepo/db' disabled because SHM infrastructure for revprop caching failed to initialize. svnadmin: E13: Can't open file '/path/to/myrepo/db/rev-prop-atomics.mutex': Permission denied * Verified revision 0. ... * Verified revision 160. I would appreciate any help or debugging hints. If necessary I can share the repository URL (but I would prefer to share it off-list to anyone interested in debugging). I can also try to debug myself, but I need some instructions telling me what to check. I didn't manage to find anything useful by googling the errors other than figuring out that the error was part of the code to fix a memory leak (http://svn.haxx.se/dev/archive-2009-08/0274.shtml). Thank you, Mojca
