Hello,
I still cannot get dovecot running with more then 1000 processes, but
hard limit is 8192 per user in box. I tried everything, including
modifying startup script of dovecot to set ulimit -u 8192. Could it be
some dovecot bug or dovecot<>freebsd bug?
I also tried to set client_limit=2 in imap service to spawn more imap
clients in one process, but still I am over 1000 processes with kernel
message:
maxproc limit exceeded by uid 89
Could anybody help? Many thanks Tomas
My system have following settings:
FreeBSD 9.0 / AMD64
Dovecot 2.1.8
kern.maxproc: 12288
kern.maxfilesperproc: 36864
kern.maxprocperuid: 8192
no limit for uid 89:
# limit
cputime unlimited
filesize unlimited
datasize 33554432 kbytes
stacksize 524288 kbytes
coredumpsize unlimited
memoryuse unlimited
vmemoryuse unlimited
descriptors 36864
memorylocked unlimited
maxproc 8192
