I have a customer running Apache 2.2.14 / mod_perl 2.0.4 / Perl 5.10.1 on Windows Server 2003 R2 SP2 (in a VMware setup).
Their error.log (with Loglevel set to debug) has many of the following errors in it: (OS 64)The specified network name is no longer available. : winnt_accept: Asynchronous AcceptEx failed. (OS 10054)An existing connection was forcibly closed by the remote host. : core_output_filter: writing data to the network and we have not been able to trace the cause yet. What are these errors typically caused by? They also get the error: :Apache2 IO flush: (620018) APR does not understand this error code at -e line 0 every 3 to 4 hours, followed by either [notice] Parent: child process exited with status 9 -- Restarting. (at which point Apache seems to have crashed and restarted itself (which it is configured to do in the Service Control Manager)) or [crit] Parent: child process exited with status 2 -- Aborting. (at which point Apache definitely crashes for good and does not restart, despite still being configured to do so). Any clues what the causes might be?
