For me, this helps to know if samba logs have the following line:

That might mean bug 341816 is not a duplicate of this one, I'll follow up on

The problem here is probably a similar one, but does not involve AIO code.

I now tend to think this is caused by the -1 not being casted to appropriate
type in:
setresgid(-1,gid,-1);
and in:
assert_uid(-1, uid);
in lib/sec_util.c as I said in bug #314657 causing problems on 64 bits machines.
But I am unsure.

I'm not sure how you've managed to hit the process limit during normal

Steve,
this could not be normal - in /etc/security/limits.conf there is no limit
