kernel panic

[Scot Loach]

Yesterday I had a kernel panic on a FreeBSD 4.7 system.  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.

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?
