Hello, bugs@freebsd.org. I posted this to comp.unix.bsd.freebsd.misc a few days ago and didn't get an answer. Since my server crashed again this morning with the same error, my sense of urgency has increased and I hope to find out whether I have indeed been the unfortunate discoverer of a bug. Could you please let me know if the problem below is known? Thanks a million!

A little troubleshooting help, por favor? I experienced a nasty crash, which caused a reboot, early this morning. The last entry in syslog before the reboot says: <date> <time> <hostname> kernel: mb_map full This error message occurs in sys/kern/uipc_mbuf.c of the source tree. Specifically, a call to kmem_malloc() in the function m_clalloc() is returning NULL. It looks to me like a request for wired memory (mbufs?) is failing. Is this a bug, or do I just need more RAM? I am running FreeBSD 2.0-R with the 2.1.0-Development#0 kernel installed. I'm using a Bustek VESA SCSI controller, if it matters. Do any kernel patches fix this problem -- or perhaps I have something misconfigured? Please consider posting if you have more information about this problem.
