i've been running zope-2.3.1 for quite some time now. everything went well. but the isp had a power failure today. and after that i kept getting too many open files, esp with access of mailhost, localfs, etc.

i've increased the file-max in /proc/sys/fs/file-max. ulimit -a tells me that i can only have 1024 file open.

if i restart zope, everything's ok. but the problem will appear again

is this the problem? Apparently, something leaks file descriptors. You must find the leak:

"lsof" seems to be a magic wand to analyse file descriptor problems. I did not use it myself, as it requires root privileges. But maybe, it can help you. I (without "lsof") would use "netstat" to determine whether sockets are leaked or files. For sockets, it is possible to determine the peers and get a feeling, what use makes problems. For files, I would use "fuser" (the weaker brother of "lsof") to find out which files are unexpectedly open or open by two many processes. As soon as the file is located, it would probably be clear, where to find the problem. Dieter
