We received the same client.c: line 378 assertion failed error this morning from
RC15 on Solaris 9 after one of our users disconnected.  I talked to the user: 
She's using Apple's Mail.app client, and she says that she had restarted her
client in order to change the IMAP server hostname to the version of the name
that matches our SSL certificate.  Below are the log messages concerning this
user and her IP address leading up to the assertion failed error:
