I have dovecot 1.0.5 installed on an OpenBSD 4.1 box and an OS X Server 10.4.10 box.
Sure you've all heard it before, because of the pipe error, no more login processes can be launched, and I have to restart the server.
dovecot: Sep 13 05:50:00 Error: pipe() failed: Too many open files ... Wondering if anyone else has seen this issue, and also in a generic problem. How are others dealing the the problem of being attacked in this method? Is there a max number of login tries for a given ip address within a period of time that I'm missing? :)
I see the same type of error on our system (Solaris 10, Dovecot 1.0.3). I've had to up the limit of file descriptors to 16384 for the "dovecot" process so that it will be able to run for a sane amount of time before running out.
The strange thing is that it normally stay around 250 used file descriptors (we have about 350 users here, not everyone using the system at the same time) and then suddenly things runs amok...
