In UNIX it is not safe to perform arbitrary actions after forking a
multi-threaded process. You're basically expected to call exec soon after the
fork, although
you can do certain other work if you are very careful.
The reason for this is that after the fork, only one thread will be running in

Hi,
When I run many heavily multi-threaded (1000+ threads/process) and
memory intensive (1800 MB+/process) processes on FreeBSD 8.0 amd64, some
of them get in STOP state in top and then seg fault and core dump. Are
stop states in top caused by seg faults or it is the OS that stops
a dump in the php.core file and not

How do I inspect the core file to find out which module caused it?

I have several jails running on my freebesd machine and lately it started to
crash when it gets a bit loaded. I followed the freebsd kernel debugging
manual, and got some output, but I have no idea what to do with it. The only
thing I think I understand of it that the bit that matters are just the
out of the startup check for now.
I 'think' I was installing a port during the last crash, but it has
been a while. I performed a fsck and a dump (to /dev/null) confirming
that both do crash the freebsd 7.2 and 6.2 (which I booted off of a
separate drive). A tar to /dev/null did run
it would let me create and have since deleted
the file; maybe that was what the reference was to. After fixing some errors,
the fsck still causes a freeze and at what seems to be about the same point.
The filesystem was unmounted for the dump and fsck has been attempted both

One thing you should try is to remove the dump_snapshot files,
because
they are supposed to be unlinked when the dump starts anyway, so
they
shouldn't be sticking around.

You probably have not created the .snap directory in the root of
the filesystem.

The .snap folders exist at all points, are set to root:operator,

Sorry to follow-up my own post; I just realized I hadn't mentioned

Try something like:
destination machine, booted e.g. from CD
newfs /dev/foo
mount /dev/foo /mntroot
cd /mntroot
nc -l 65000| restore -rvf -
source machine
dump -0 -a -C 8 -L -u -f - / | nc dest 65000
