[Dovecot] Corrupted index cache file

Hello

I got this error yesterday

dovecot: Feb 11 16:07:27 Error: IMAP(dumontj): FETCH for mailbox Sent UID 7139 got too little data: 11112 vs 11160 dovecot: Feb 11 16:07:27 Error: IMAP(dumontj): Corrupted index cache file /user/dumontj/.imap/Sent/dovecot.index.cache: Broken virtual size for mail UID 7139

Does remove the cache will cure the problem ?

Thanks
