[Dovecot] imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument

[Angel L. Mateo]

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? Any pointer to this problem for ubuntu 
kernels? Or for generic 3.0 kernels?

	Any idea?
