very long cyr_expire at startup and no mail delivery

[Marcus]

Hi,

because of a kernel update I had to restart my server. After the restart
cyrmaster was running, but I couldn't connect to imap or pop3 port and
sendmail couldn't communicate via socket with cyrus. A "ps ax" showed a
running "cyr_expire" process for about 20 minutes. After the cyr_expire
process finished everything worked fine again.
 Question now: is there a way to avoid such long cyr_expire checks at
startup or how to do a check by hand before shutting down the cyrus so a
startup would become quicker?

System: Debian/lenny 
Cyrus: 2.2.13-14+lenny3
Sendmail: 8.14.3-5+lenny1

Thanks,
Marcus

P.S.: I think this cyr_expire problem might be related to my "FATAL:
lmtpd: unable to init duplicate delivery database" I posted in April.
