Hello
I got this error message yesterday evening for a user I've checked LDA error log it happened 6 times in 3 days for 5 differents users, not much but I wonder what's going on as actually the server is moderately loaded ( Easter holidays ) we have currently 250/300 IMAP processes , in "normal" production time we have approx 1000 IMAP processes running.
Apr 14 19:24:37 imap(xxxxxxx): Error: FETCH [] for mailbox Drafts (Hugues at ESIEE) UID 17836 got too little data: 16384 vs 18012 Apr 14 19:24:37 imap(xxxxxxx): Error: Corrupted index cache file /var/cache/dovecot/index/xxxxxxx/.imap/Drafts (Hugues at ESIEE)/dovecot.index.cache: Broken virtual size for mail UID 17836
The machine is supposed to be HUDGE for our 4000 mailboxes HP Proliant DL380 G7 , 12 Gb RAM 24 cores !!!
I've located index/cache files on another disk than users mailboxes
mailboxes are living on a 2Tb RAID array ( 50% full ) index/cache are living on another single disk ( 10% full )
I run Dovecot 2.0.11 + dovecot2-pigeonhole compiled from FreeBSD 8.2 ports
Dovecot or hardware problem ???
Thanks a lot for any ideas/infos
