[Zope-dev] hanging zeo clients
Hi!
We have one ZEO server that handles 3 FileStorages and 8 ZEO clients
connecting to the ZEO server.
Sometimes a client hangs and does no longer handle incoming connections.
The ZEO server log shows in such a case, that the (hanging) client
initiates a new connection
2006-11-12T10:30:39 INFO ZEO.StorageServer (3958) new connection
('10.x.x.x', 32803):
If I'm correct, the next that should happen is a log entry from the
ZEO server that he received a handshake from the client. Something
like
2006-11-12T11:12:46 INFO ZEO.zrpc.Connection(S) (10.x.x.x:36805)
received handshake 'Z303'
This never happens. I have to restart the client.
Has anyone an explanation for the hanging clients?
(We're using Zope-2.8.8, Python-2.4.2)
Markus

Re: [Zope-dev] zeo server conflict resolving
Hi Stefan!Forgot to mention that this was actually the first thing I tried. But it doesen't work, asthe INSTANCE_HOME dir does also not show up in sys.path (in find_globals). - Markus On 6/2/06, Stefan H.

[Zope-dev] zeo server conflict resolving
Can someone please enlighten me on conflict resolving of the zeo server?I'm getting occasional conflict errors from the zeo server.The class I'm getting those conflict errors is a simple class(only inheriting from Persistent) that defines a _p_resolveConflict() method. What I found out so far is, that in FileStorage.store() if serial!=cached_tid thentryToResolveConflict() gets called. In this method, in order to resolve theconflict, find_globals tries to import the module where my class is defined. Here's the problem. The zeo server has no information about my Products dir.I added it to the PYTHONPATH variable in zeoctl before starting the server.If I do a 'zeoctl show python' the Product dir shows up in the path, but when I log sys.path from within the find_globals() method it does NOT show up.How can I teach the zeo server to lookup my Products dir to resolve the conflict? - Markus ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Please vote about conflict errors logging
1. Do you want these ConflictErrors retried logs to be at level:INFO 2. In addition, please specify if you feel those retriedConflictErrors should have their full traceback logged? no, without traceback 3. Finally, please tell us if the ConflictErrors that *can't* be retried (and are returned to the user as an error, and are alsologged to the error_log) should be additionally explicitely logged tothe event log, and at which level:ERROR ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
