Strange continous SEVERE error after upgrading to APR 1.3, Critical poller failure, Timer expired
Hi, After we upgraded APR from 1.2.8 to 1.3.0 we get a strange error in tomcat's catalina.out that we have never seen before: Jun 24, 2008 11:42:09 AM org.apache.tomcat.util.net.AprEndpoint$Poller run SEVERE: Critical poller failure (restarting poller): [62] Timer expired This is repeated over and over, at approximately 5-10 times per second. If we switch back to APR 1.2.8, and not touching anything else, then this error message goes away. We use Tomcat 5.5.23 on Solaris 10 (Sun X2200 and X2100). We have tried with APR 1.3.2 and the result was the same as for 1.3.0. As far as I can tell, a regular poll time out should not result in this error, but still I tried increasing the pollTime from the default 2000 (2ms) to 2 (20ms) for the connectors in server.xml (http://tomcat.apache.org/tomcat-5.5-doc/apr.html) but that didn't change anything. I have investigated the tomcat process using the truss command (like strace I guess, but for solaris) right from the tomcat startup, and this is the first 3000 lines of the output: http://pastebin.com/f60671b83 If you search for ETIME (the name of the error message Timer expired) you can see that the first occurence (at line 2545)is at about 1 second after startup (so it seems that it is not triggered by a request). The thread in questions is thread number 6. Here is the truss log file for the first 20 minutes or so, filtered to only include the thread 6: http://pastebin.com/f3fd14e2c There were also other threads that experienced this Err#62 ETIME, but thread number 6 seems to be the one with the most number of these errors. Also, when restarting tomcat it is always the thread number 6 that has the this error first and has the most number of occurences of it. Does the message Critical poller failure (restarting poller): [62] Timer expired or the truss log output tell you guys anything about what can be wrong? Could it be a bug? Is there something wrong with our web application? The thing is that we haven't noticed anything wrong with it so far, besides these annoying error messages in catalina.out.

Until httpd v2.2.10 is released against the newer version of apr, simply replace the bundled version of apr with the newer one containing the fixes you need.

Should I delete the srclib/apr and srclib/apr-util directories I built just yesterday? Remember, the configure took me over five hours to build what I have (and it doesn't work) You don't need to delete it, but you'll have to run another round of configure on the new APR/APR-util anyhow. It's really unfortunate the environment is so slow. Any way you can do this on bare metal somewhere so you don't have to wait for hours to see the results? 2. Where should I upload apr-1.3.2.tar.gz? in srclib? No need. You can put it anywhere you like. But, if you replace apr and apr-util directories inside srclib with release 1.3.2, it should work as well. 3. Does this contain both apr and apr-util? No. APR-util is separate (i.e. you need to download another tarball). 4. I find no install instructions; what are the steps? [small mercies: I know how to unzip and unwind; but once there, what can I expect? APR and APR-util are separate packages from httpd (httpd folks do ship both with httpd for convenience). but that's one reason I'm so pissed: apparently the version shipped with httpd is not the correct version. This would never be tolerated in the mainframe world. They can be installed by themselves. They get installed like this: but wait: I do the gzip to unzip, but do I need to use pax, in order to convert to EBCDIC, or can I just use tar? APR: -- ./configure [various options you like here] make make install -- APR-util: -- ./configure --with-apr=/where/apr/is [various options you like here] make make install -- Run ./configure --help to see all the options. Once you're done with those two, you can build and install httpd in a similar way: httpd: -- ./configure --with-apr=/where/apr/is --with-apr-util=/where/apr-util/is [various options you like here] make make install -- Again, run ./configure --help to see all the options. 5. So suppose I install apr and apr-util under srclib, will I need to run the Apache configure again? Yes, that's correct. Given that this runs for such a long time, it would really be better to do it on the hardware, rather than an emulator.

So while that bundled version of APR may not be correct for your particular platform, I don't really find that too surprising given the circumstances. Certainly lots of people have built httpd-2.2.9 and dependencies from the tarball on other systems. Well, from my perspective, I wanted to install the current Apache, httpd version 2.2.9; I downloaded the tarball and went through the install process as directed. Only to find the version of apr and apr-util included are apparently not in synch with the httpd in the same tarball. That's why I'm doing this: the configure of httpd aparently went OK, but the make failed, and someone told me it could be cured by installing the current version of apr and apr-util. That's my perspective of what's happening. I find it very surprising a bundled version of a subsystem would not be a good fit for a platform, especially if there is an appropriate fit available. Why wasnt apr-1.3.2 included in the httpd-2.2.9 tarball, I guess is what I'm asking. I had never even heard about apr before this effort. It's the server I was after. But what do I know. I swore off mainframes when they started to implement POSIX-like subsystems in order that people could actually get anything done on them. Huh? People have gotten a lot of productive work on mainframes before POSIX-like things. z/OS now supports POSIX so that you can run classic mainframe work at the same time you are running UNIX type tasks. In fact, running under the shell you can access both UNIX files and classic MVS files from the same program. And, running outside of a shell, a program can access both classic MVS files and HFS files. Please remember that when I grew up in the business (starting in 1968(!)), working for IBM, UNIX was considered the enemy. Now, I'm trying to understand how the two worlds can work together and compliment each other. It's a fun journey! Also the local utility refused to lay in the cable to power up my pet PDP-10 ...

It is indeed that fix that breaks it. When I revert

Hi,
After we upgraded APR from 1.2.8 to 1.3.0 we get a strange error in

Jun 24, 2008 11:42:09 AM

Could this be related to
http://marc.info/?l=apr-devm=121347872322492w=2
I had something similar with httpd+Event MPM on solaris.
Current workaround is to use Worker MPM.
OK, I've just tested APR variants with Event MPM.
It is indeed that fix that breaks it. When I revert
the fix, the problem goes away.
The original patch posted to fix the same bug works fine.
Can I suggest you apply the following patch to 1.3.x
(should work on 1.3.0 or 1.3.2 too) and let us know if
it fixes the problem you're seeing?

Looks good and makes sense.
apr_get_netos_error() in case of ETIME = 720062
APR_TIMEUP = 70007
So they are different.
But I would do
rv = apr_get_netos_error();
instead
of
rv = APR_EGENERAL;

Good observations. Folks, you want to fix these regressions before
we TR 1.3.3?

Starting over
Well, a disk failure has caused me to have to start my port of Apache to z/OS over again. Bit of a bummer, but also a chance to start over with a clean slate. Based on some of the suggestions and posts, I find I'm bewildered a bit by the open source world. For example, Greg Ames asked me: Where did you get your build tools, especially libtool? It never would have occurred to me to scuttle around grabbing build tools. My experience is: you get an application, whether for Windows or z/OS, and you install it. Install shield, or its cousins, either come with the package or the OS; in the z/OS world you either simply unpack (RECEIVE) or you use SMP/E, which is part of the OS. So, help me out here. How would I find out the right tools to grab to build Apache for my environment? I'm trying to write a narrative, to direct those who follow, in a linear (or relatively linear) or rational (or relatively rational). If I were rational, I guess I would start with the Apache site: Apache.org, which has a link to the httpd project (httpd.apache.org) which contains the following interesting / promising links for my efforts: Download ( http://httpd.apache.org/download.cgi ) Documentation, Version 2.2 ( http://httpd.apache.org/docs/2.2/ ) The Download site tells me Apache 2.2.9 is the best available option, and gives me two Unix sources, three Windows sources, and an Others; none of these mention z/OS, so I'll take the closest to this, which is Unix; the first choice is a .gz file, the second is a .bz2 file. Either way, I'll have to download a file to unzip the tarball. I choose the .gz file because the z/OS Ported Tools page has a port for gzip. You see, I can make some basic deductions and apply some reasonably knowledgable reasoning to select the files I need. But then... No clues on the Download page about installing. So, I roll over to the Documentation page, which has lots of interesting links... Under Reference Manual I see Compiling and Installing hey, that looks like just the thing! Go there ( http://httpd.apache.org/docs/2.2/install.html ) And I am told pretty clearly that I will need libtool and autoconf. Now please remember I am a stranger in a strange land. There is no definition nor link to any place to get these tools. Where do I go? What do they do, anyway? You could help the cause a lot by providing this kind of information. I know that people who know know. Reminds me of the ancient days of mainframes when the systems people were kind of high priests and were jealous of letting their knowldege be widely available. Anyway, Google ends up pointing me back to the IBM Ported Tools page, which contains a large tarball with lots of tools, including libtool and autoconf. Of course, I have no idea if these are right for Apache 2.2.9 on z/OS 1.9. But we'll give it a try. OK, so I'm off. We'll send back dispatches from the trenches.

Steve, you shouldn't need to reinstall libtool or autoconf, in fact as of 2.2.9 (and apr 1.3.2) these were bleeding edge. You only need such things if you were to run ./buildconf, which I don't suggest you do. I think Greg may have confused you further. We use these to create the tarball you obtained so that you don't have to grab anything (except compiler, linker etc etc). Sorry bout your disk crash :( Bill
