Hi,
I'm not a list member, so please Cc: me on any responses. Thanks.
Unfortunately I am not able to give too much information here, but I'll
give you what I've got. First, the scenario. I'm copying a bunch of files
(>4GB total, no file larger than say 200k though) from a 3.2 box to a
4.2-RELEASE box that has quotas enabled. This had caused the system to crash
a few times so I put in a debugging kernel.
The uname -a:
FreeBSD xxx.xxx.xxxxxx.net 4.2-RELEASE FreeBSD 4.2-RELEASE #1: Wed Feb 14 16:23:31 PST 2001 root@xxx.xxx.xxxxxx.net:/usr/src/sys/compile/XXXXXX i386
Here's the kgdb backtrace. Note the lack of any information about 'dqget'
or 'getinoquota'. In fact, there was no information in any of the calls
until I entered 'symbol-file kernel.debug'. Anyways, I hope someone here
could point me in the right direction for getting information out of gdb
regarding the dqget/getinoquota calls (this would be MUCH appreciated) -
they're clearly where the problem is:

For now I'm disabling quotas on the box, but this is a less than optimal
solution. Any thoughts?
