That's kind of pointless, sorry. I really need a trace of the imapd
process, since that's what's locking up.
The only interesting bit is:

All we ever got was the "1 CAPABILITY" response (14 characters) without the
actual contents of the capabilities.
A trace of the connected imapd would be a lot more useful. You should be
able to figure it out by following the port numbers (I would use netstat
on Linux for that, or lsof - not sure what you do on Solaris)
Hmm - I don't see any code that can generate "1 CAPABILITY" - it's all
either "* CAPABILITY ..." or "<tag> OK [CAPABILITY ...]"
Sorry - I need more debugging info (and probably your imapd.conf) to
have a chance of understanding what's going on!
