Hi Zope gurus,
After upgrading to Zope 2.6.1 on Linux, when submitting forms, we sometimes get this error:
Site Error ... exceptions.IOError ... Traceback: Module ZPublisher.Publish, line 150, in publish_module Module ZPublisher.Publish, line 114, in publish Module Zope.App.startup, line 149, in zpublisher_exception_hook Module Products.SiteErrorLog.SiteErrorLog, line 195, in raising Module Products.SiteErrorLog.SiteErrorLog, line 206, in _do_copy_to_zlog Module zLOG, line 130, in LOG Module ZLogger.ZLogger, line 16, in log_write Module ZLogger.stupidFileLogger, line 27, in __call__ Module ZLogger.stupidFileLogger, line 90, in stupid_log_write IOError: [Errno 5] Input/output error ...
It's terrible hard to debug as it happens sporadically, not consistently, and we don't get any more debug info than this. Even worse, we have a standard-error-message that emails errors to us, but it fails to do anything in this case. Any ideas what could be wrong and how to troubleshoot better? The disks have plenty of free space; after restarting, or waiting a while, things work again.
This usually means Python is trying to write to stdout or stderr and failing because stdout/stderr don't go anywhere. Make sure you have a log file configured (using the EVENT_LOG_FILE environment variable, rather than the old STUPID_LOG_FILE).
