Greetings,

Occasionally, I will find one of my servers (running Debian/Lenny with back-ported slapd version 2.4.17) in a state where the following occurs:

* Write operations will 'freeze' - leaving the requester at a frozen prompt or frozen LDAP-client of some kind (from wherever the write-operation originated). * slapd refuses to 'stop', even though it indicates that its waiting for "0" processes to complete. * Logs do not indicate a segfault nor any poorly terminated processes. * Read operations on same server continue to function normally. Any data that existed before the "freeze" is returned as it should be.

Modules used:

* accesslog * back_hdb * back_monitor * back_relay * back_rwm * syncprov

Servers are all fairly new, and reasonably beefy for their purposes:

* 6GB RAM * 2+ GHz CPU, all QuadCore Xeon and all running amd64 kernel (current with Lenny) * Plenty of Disk Space (gigs and gigs) * Servers are SLEEPING (0.00 avg load)

slapd is making use of 'tool-threads' with a value of '4' - however changing this value has had no effect - Just a side note.

Inform me of any further configs and/or information that you need, and I will provide it promptly.

Thanks,

Jeff
