Re: slapd stuck in sched_yield() call

Hi all,

I've got an openLDAP read-only replica running on a server, and I noticed
today that it is using 90-95% of the CPU and it is looping in
sched_yield()  system call (according the strace).  It really should not
be doing anything  as no changes are being made to the master LDAP
repository at all.  Could  this be a bug?  I am running 2.2.6 (the latest
RPM from SUSE) on this system.   As it is only a failover system I'd
rather have an easy-to-manage RPM than  the latest and greatest.  But
maybe this is a known bug that I am running  into?  It would only concern
me because it seems to be pegging the CPU.

OpenLDAP 2.2.6 was a very buggy release. The best release to run is OpenLDAP 2.2.20, especially because of the fixes that went into 2.2.18, 2.2.19, and 2.2.20 that closed out some long standing bugs. I understand that you may not want the latest and greatest, but you *will* experience a number of problems with 2.2.6.
