Today I got quite a scare. At 16:50 I couldn't do almost anything, getting an error message about too many open files in system. At about 17:00 all came back to normal. I did `lsof' then, and it reported 913 open files, about a third of them belonging to apache/postgresql. After restart of apache, the number went down to 730. The system log contains: ,---- | Oct 21 16:50:26 soup syslogd: /dev/console: Too many open files in \ | system: Too many open files in system | Oct 21 16:50:26 soup syslogd: /var/run/utmp: Too many open files in system | Oct 21 16:50:26 soup syslogd: /var/run/utmp: Too many open files in system | Oct 21 16:50:26 soup /kernel: file: table is full `---- What could have caused this? The box runs 4.1-S, and the main services are apache/mod_php4, postgresql, and a UW IMAP server (private: not a busy one). No X. Could this have been an external attack? If there is a limit on the number of open files somewhere in the kernel, is it raisable? Many thanks, -- Arcady Genkin Don't read everything you believe.
