  I have Cyrus 2.4 with thousand mailboxes and separated partitions for 
data and metadata, with squat files in metamaildata partitions.

Every night at 2 I run "squatter -s -a -i" to update the indexes.

Two nights ago a metamaildata partition filled out. Starting from 2am 
many GiB busy in few hours. I can't understand why. No errors in Cyrus 
logs. I didn't find the files which caused the busy space.

Last night squatter didn't reproduce the error.

Do you have ever experienced problems like this?

Thank you very much for every hints.
Kind Regards
