While testing various load scenarios, slapadd deadlocked on me.
The trace for thread 1 and 2 look identical, so I'm assuming they're the same thread. In that case I see 3 tool threads running. How many did you have configured? If 1 and 2 are really different threads (certainly their thread IDs look quite different), then there's something very wrong in the thread library...
print bdb_tool_index_tcount
It looks like one thread has exited early. I'm not sure how that can happen since the only way for any index thread to exit is if slapd_shutdown is set. Is it set?
