Looking at the core dump, it was caused by a corrupted uidinfo pointer referenced by a tcp pcb. I searched through the archives and found an identical stack trace in this message from 2000: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=322837+0+archive/2000/freebsd-s table/20000625.freebsd-stable This was apparently fixed by a patch discussed in this thread. http://www.geocrawler.com/archives/3/171/2000/11/0/4718890/ The patch was applied to version 1.66 and 1.67 of /sys/kern/kern_resource.c I browsed through the CVS for these changes, but found no evidence of them ever being merged to RELENG_4. This is a real memory corruption in the kernel. If these changes were never merged, does anyone know wny? Can anyone suggest a course of action to resolve this?
