[Condor-users] condor 6.6.2 suddenly started seg faulting

[filipdef@xxxxxxxxxxxxxxxxx]

Hi,

I have condor 6.6.2 running as the central master on a
SuSE 9.0 box, and it's been running great for the last
several months.

Now, today it suddenly stopped working: when trying to start
any condor command or when trying to start the daemons,
I immediately get a seg fault.. When doing an strace on
the command, the last line I get is something about
/etc/nsswitch.conf:

--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

There's been some work on DNS and stuff, but as far
as I can see everything on that side is all working
smoothly.. Nothing in the machine itself has been
updated and nothing else seems broken..

Anybody any ideas ??? This is a production system, so I'd really
like to get it back up sooner rather than later...

Thanks in advance for any help!!
