openldap 2.1.30 SIGPIPE?

Hey.  So, we're trying to avoid going to 2.2.

After attaching to slapd with gdb, we appear to get one or more SIGPIPEs, which end up crashing the server after somewhere around 24-48 hours of heavy use:

I'm not an experienced "gdb" user, so let me know what to do if there's some way of getting the backtrace to provide information.

I looked for SIGPIPE in the archives, but most of the issues related to client-side problems. Does this symptom suggest any possible remedies?

Thanks very much!
