I am experiencing problems with back_meta. It does return search results for some time, but at some point starts returning empty search results, with SEARCH RESULT err=32 in the logfile. This often (but not always) happens after 5 - 30 minutes.

It doesn't return data from either of the ldap servers it is connected to. The problem also occurs in a minimal configuration with just one "uri" defined.

After slapd is restarted, it again works properly for some time.

When running in GDB, I get the following backtrace:
