1. Is there any useful information that can be obtained from these log entries, or do we simply need to change to a more verbose log level and wait for slapd to die again? 2. If we need to change our log level, what is a suggested level? Right now we're using "loglevel sync stats". Would it be wise to change the log level to -1 (any)? These are production servers, and I imagine that'd be a huge performance hit. 3. Also, we're logging asynchronously at the moment. Should we disable this while debugging?I would suggest you (a) Upgrade to 2.4.21 (b) Fix your tcmalloc build (c) If the problem still occurs, run slapd under gdb so you can get a backtrace of some kind. Make sure your OpenLDAP build, etc, has debugging symbols. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
