Some people had this problem when giving some superoptimization flags with Sun Studio. Did you do that? -Timo
No I did not use any optimization.
And Dave, I took what you said and just tried both dovecot-1.0.2 dovecot-1.0.rc29
and have the same exact results :(
We are also seeing lot's of problems with high CPU utilizations on Solaris 10, but in the IMAP daemon. We found one way around it and that is to disable the IDLE support. By disabling IDLE our CPU load went from 100 to 3 (on a 6-core Sun T1000 (looks like a 24 CPU machine). We typically have 100-300 users accessing this server using POP3 and IMAP.
We also saw a lot of pollsys() calls when trussing it. We haven't had time to debug it further though. I tried compiling the source file that calculates the ioloop timeout using "-O" instead of "-fast" but that didn't make any difference.
