v2.3.15 IMAP connection hangs

[Rosenbaum, Larry M.]

I have just installed v2.3.15 on Solaris 9 Sparc with Cyrus-SASL 2.1.24rc1.  When I connect to the IMAP port, I get a banner message but there is no response to any command I give it (including "0 logout").  I am able to give commands to the POP3 port and LMTP port just fine.  Previous versions of Cyrus IMAP work OK too.  Where should I look for the problem?

Thanks,
Larry
