Well, I went ahead and built just the minimal tcmalloc (and upgraded it
to 1.5 while I was at it), since that seemed to be something that
needed to be fixed anyway. I installed it to one of our replica
servers, and it ran for about 3 days, and then slapd died again this
So next I'm gonna upgrade to 2.4.21. I'll probably do it on just one of our replica servers for now.
1. A 2.4.21 replica should work fine with a 2.4.19 master, correct?
2. On the machine I upgrade, can I just stop slapd, upgrade, and start slapd again, or should I slapcat/slapadd?

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
