Losing NSS access

Hello,

We are running OES2015 on SLES11sp4. On Sat afternoon 1/19 we had some employees working on the weekend and I was notified via email that over server was down.
I was able to VPN into our network and restart the server remotely and all was ok. Today Monday 1/21 we had another instance of it going down. Also, another reboot was necessary
to restore access. I would like to try to find out the cause.

Now, when I say the server went down it actually is just that the NSS volumes become inaccessible. We have 2 volumes that are mapped when users login. A USER volume mapped to P: and
a SOFTWARE volume mapped to R:
The rest of the login script maps to SYS (F:) ; and V:, W:, X:, Y: and Z: are all search drives.
I've noticed some users have used one of these search drives instead of the P: or R: volumes. I have told them not to use these.
My question is could that have caused the issue or if not where can I proceed to look to find out.

If I need to provide more info let me know.

Thanks,
Tom

Re: Losing NSS access

Hard to rate with the info provided. I'd start with checking /var/log/messages and dmesg output with an eye on the timeframe in question. Look for stuff such as pagefaults which could e.g. reference libncpengine.so. Another possible reason could be a hardware fault on the device(s) the NSS pools are residing on (you'd see device deactivations then). When you dialed in to bounce the box, did run something like "ndsstat"? Are the any cores in "/", "/var/crash" or "/var/opt/novell/eDirectory/data/dib"?

you could try to run "poolverify" just in case there are any structural
issues.
