slapd general protection libtcmalloc_minimal

[fcjoe]

OS: 64 bit Ubuntu 10.04 LTS (patched)
ZCS: OSE Zimbra 7.1.1 GA (patched)

I'm trying to find out why my server gave up on communicating with the world early this morning. I have a

__ratelimit: 15 callbacks suppressed
slapd{22110_ general protection ip:xxxxxxxxxxxx sp:xxxxxxxxxxxx error:0 in libtcmalloc_minimal.so.0.1.0

pair of errors around my most suspicious time interval. I don't think the ratelimit is particularly important, but does the slapd error tell me anything I should be worried about, or do I need to look in another direction?

Thank you.

After upgrading to 7.1.2 on Ubuntu 10.04.3 x86_64, I'm seeing slapd crashes with a similar error.
