Hello.
dovecot-1.0.3 compiled with kqueue support periodically stop to accept
connections:
Listen queue not empty:
Current listen queue sizes (qlen/incqlen/maxqlen)
Proto Listen Local Address
tcp4 6/0/8 *.143
however kevent return 0 pending event:
truss -D -p 71851
0.000000000 SIGNAL 17 (SIGSTOP)

How I can debug this problem? It may dovecot bug as well as kernel bug.
How I can see list of knotes corresponding to given kqueue?
I try to see kqueue->kq_knlist (via kgdb), but it always empty, even
when dovecot work properly.
