NSCD Segfaults - Bug or incorrect configuration?

kaitocracy · 2010-04-22 23:12:58

Hi, my NSCD is segfaulting a couple of times a day. The only record I have of it is:

LINODE2: 04-22-2010 09:35:01 [kernel] nscd[31604]: segfault at a ip b776bcdb sp ae91a9dc error 4 in libc-2.11.1.so[b76f8000+141000]

I don't know if it is possibly due to me configuring it incorrectly. Here is nscd.conf

Can someone take a look and tell me if I should file a bug report?

There is a bug report here: http://bugs.archlinux.org/task/19157 . So far I have not been able to figure out what is going on. Given you appear to be using Linode, I doubt this is a suspend-to-ram issue that the bug report suggests.

Edit: try

enable-cache        hosts        no

Thanks for the answer. It turns out though that the hosts cache is actually the only one that is important for me...

So did that actually work to stop the crashing?

I don't know yet, it usually crashes a couple times a day so I'll wait and see.

OK, great... if that is the issue, at least then I have some place to start hunting this down.

I changed the configuration to disable host caching and it hasn't segfaulted yet...
