OK, the backtraces helped a lot. Thread 6 hit the assertion while trying to close the connection, and thread 5 was already trying to close the connection. And Thread 5 was waiting for thread 2 to wake up and give up the connection handle. Seems like a bug in connection.c, aggravated by the presence of persistent searches on the connection.

(continuing the openldap-software thread starting at http://marc.info/?l=openldap-software&m=120654684131594&w=2)

An assertion failure causes slapd to crash every few days in our environment. The assertion seems to be in servers/slapd/connection.s:680:

 assert( c->c_writewaiter == 0);
