Hi,
since some days (about 10) I get the following error in mail error log many, many times:
...
dovecot: imap(user@domain.com pid:32769 session:
It's always the same "dovecot.index.cache" file and only for the same heavily used account. The account is currently used from about 10 different clients with imap at the sime time.
I checked the size of the index cache file and it seems very big:
total 2,7G -rw------- 1 mailstore mailstore 464 Mär 24 14:36 dovecot.index -rw------- 1 mailstore mailstore 464 Mär 24 14:36 dovecot.index.backup -rw------- 1 mailstore mailstore 2,7G Mär 24 14:19 dovecot.index.cache -rw------- 1 mailstore mailstore 140 Mär 24 14:45 dovecot.index.log -rw------- 1 mailstore mailstore 89K Mär 24 14:36 dovecot.index.log.2
About 2,7 GB?
To solve the problem temporarily, I removed the index files from the index Trash folder and Dovecot initialized an index rebuild. Now the size of the index files are small:
total 28K -rw------- 1 mailstore mailstore 512 Mär 24 14:47 dovecot.index -rw------- 1 mailstore mailstore 20K Mär 24 15:28 dovecot.index.cache -rw------- 1 mailstore mailstore 1,2K Mär 24 15:28 dovecot.index.log
But why could the index cache file be so big?
Many thanks Urban
