Hmm, and this happens on all x86 platforms?
I'm the maintainer of cyrus-imapd rpms and there was already a big
surprise with nptl kernels in combination with db4. Interestingly the
problem appeared only on AMD K6 and Athlon CPU's. The following error from
cyrus-imapd showed up in syslog:
May 15 13:51:25 co ctl_cyrusdb[10520]: DBERROR: dbenv->open
'/var/lib/imap/db' failed: Function not implemented
This was with the original RedHat kernels as well as on XFS enabled ones.
The solution was to rebuild db4 without --enable-posixmutexes. A modified
spec to rebuild db4 from RedHat is here
http://home.teleport.ch/simix/RPMS/Cyrus-imapd/DB4_for_RH-9/db4.spec
Is it possible that the nonnptl db4 package is a solution for the problem
discussed here? I'll just try it but can someone tell me what problem I
should expect if this fix doesn't work. Does rpm not work at all?
