Zlib problem - dovecot.index.cache

[julio covolato]

Hi

I'm having problems with zlib giving an error in dovecot.index.cache, 
when I move a message from one folder to another, this error often 
appears "Cached message size smaller / biger than expected":

Feb 03 19:02:07 imap(julio at xxx.com.br): Error: Corrupted record in index 
cache file 
/var/spool/vmail/vmail01/xxx.com.br/julio//Maildir/.Trash/dovecot.index.cache: 
UID 503914: Broken physical size in mailbox Trash: 
read(zlib(/var/spool/vmail/vmail01/xxx.com.br/julio//Maildir/.Trash/cur/1612388618.M2222P27195.saturn,S=34225,W=34342:2,S)) 
failed: Cached message size smaller than expected (34225 < 40960, 
box=Trash, UID=503914)

I'm using the [1] dovecot-maildir-compress.sh script in crontab daily to 
compress old messages with 7 days old with bzip2.

Crontab line:

30 2   *   *   *  /usr/local/sbin/dovecot-maildir-compress.sh -t 7 
/var/spool/vmail/vmail01/ > /dev/null 2>&1


Any suggestions on how to fix this error?
