Hi,
I'm not an expert on these things but I had success lately debugging some
problems on linux. First I used strace in ltrace on follow mode:
strace -f /path_to_cyrus/master
ltrace -f /path_to_cyrus/master
While it produces lots of output, you can easily catch it in a file and
examine single processes by grepping the pid.
Then, I tried creating a backstracke of killed imapd processes. I
installed a debugging imapd binary in /path_to_cyrus/ and set 'ulimit -c
100000000' to make it dump core. Then I started cyrus-imapd until various
core files showed up in the imap spool directories. Now I ran gdb on the
core file and produced a backtrace which showed the exact place where the
problem in the code was.
I'm not sure about the equivalent commands on Solaris 9 but I'm sure
you'll find out.
