[Dovecot] Upgraded from alpha 3 to 4 getting errors

[Andy Cravens]

I just upgraded from alpha 3 to alpha 4 and now I'm getting these errors:

dovecot: Nov 28 16:17:37 Info: Dovecot v1.0.alpha4 starting up
dovecot: Nov 28 16:20:11 Info: imap-login: Login: user=<jdoe>, 
method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS
dovecot: Nov 28 16:20:13 Info: imap-login: Login: user=<jdoe>, 
method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS
dovecot: Nov 28 16:20:13 Error: imap(jdoe): flock() locks not supported
dovecot: Nov 28 16:20:13 Error: child 15661 (imap) returned error 89

I'm using maildir so locking shouldn't be an issue.  Mail storage is NOT 
nfs mounted.  I'm on Solaris 9.

Any ideas?
