Yay, things are getting worse. Increasing maxsockbuf caused crash after 2-3
hours. There was no crashdump and the last thing in log was:

Apr 11 12:32:40 lsm-gw kernel: ad4: FAILURE - out of memory in start
Apr 11 12:33:00 lsm-gw last message repeated 125 times

I suppose, I'm hitting some kind of kernel memory limit, maybe because of leak.
Any ideas, how can I track it down?
