cyr_expire[14157] trap divide error

[Rudy Gevaert]

Hi,

I'm seeing the following message in my kern.log every morning when 
cyr_expire is run:

cyr_expire[14157] trap divide error ip:4432d5 sp:7fff96f38c90 error:0 in 
cyr_expire[400000+136000]

When I run gdb with the core file I see:

Core was generated by `/usr/cyrus-2.4.6/bin/cyr_expire -C 
/etc/cyrus-ugent/conf/mail21/imapd.conf -D 3'.

I provide the full core dump uppon request.

Thanks!
