Hello,
More problems (it seems that we won't be able to put our new servers in production). The problem now is that when we reach 1000 dovecot processes we have errors like:
Jul 9 12:10:22 myotis31 dovecot: imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument Jul 9 12:10:22 myotis31 dovecot: imap-login: Fatal: master: service(imap-login): child 32251 killed with signal 6 (core dumps disabled)
and server doesn't accept any new connection.
Our servers are running in ubuntu 12.04 with kernel 3.2.0-24-generic kernel. I have found a similar problem at https://bugzilla.redhat.com/show_bug.cgi?id=681578 but it is for redhat kernel of series 2.6.
Could be the same problem?
It's definitely the same problem.
Any pointer to this problem for ubuntu kernels? Or for generic 3.0 kernels?
Sorry, no idea.
in case its fixed in some more recent versions
http://kernel.ubuntu.com/~kernel-ppa/mainline/
guess this is latest for 12.04 http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
