Why would I use a source rpm from FC2? :) It's Centos/RHEL 4's cyrus-sasl rpm. Specifically, the cyrus-sasl-sql rpm. It appears all other code seem to work except for the sql plugin. I am not sure if that is due to configuration error, which seems unlikely since i copied the configuration for smtpd.conf from the FC2/Opteron box, or due to threading /sasl initialization issues. > > >> An attempt to get a backtrace gives these results: >> > ------------< snip <------< snip <------< snip <------------ >> All traces show the crash in _dl_sysinfo_int80 for those who are >> interested in licking this one.

All I could find from searching on the '_dl_sysinfo_int80 ()' string was something about threading or hyper-threading being enabled causing crashes...does Pentium 4 2.8 Ghz cpus have hyper-threading? > > The debug RPMs are stored at http://vault.centos.org/debuginfo *but* it > appears that the cyrus-* rpms are missing.

Anyway, I recompiled the cyrus-sasl source rpm after enabling another plugin that I could make use of and now things are working for me...the the rebuilt sql plugin still crashes but the other plugin allows me to make use of the mysql tables I have without doing pam_mysql. I wonder what is it that is causing the crashes...the logs tell me that postfix initiated sasl initialization and then it crashes with no other information...but I guess I can drop it now... regards, feizhou
