>Description:
Yesterday evening my previosly rock-stable www/ftp server
crashed with kernel panic. Just before crash kernel wrote:
Apr 10 21:48:59 www /kernel: All mbuf clusters exhausted, please see tuning(7).
Apr 10 21:49:30 www last message repeated 29 times
I was prepared (better safe than sorry) and have crashdump.
I will supply any additional information to help fix this.
I can increase number of mbuf clusters but believe kernel
must not panic even in such situation.
Here is gdb backtrace.
