iptables -A INPUT -p tcp --syn --dport 143 -m connlimit
--connlimit-above 8 -j REJECT
This will limit established imap connections to 8 per ip

I have gdb'ed the locked process, backtrace is below. It seems that
problem occurs when imapd process catch a signal when is inside malloc()
call. The signal handler has a malloc() call too, so finally there is
interlock between two mallocs
I have

Jonk, thank you for the idea. Somewhat looks strange as old

would appear the lock process has changed since I last looked at this,
so this may not be a help at all.
Good luck,
John
