Poolmon: Problem with index-locking

[Tom Sommer]

I have Poolmon (https://github.com/brandond/poolmon) set up. When it 
does all the checks concurrently, obviously there are locking issues on 
each mailserver it tests:

"Warning: Locking transaction log file 
xxxx/indexes/dovecot.list.index.log took 60 seconds (syncing)"

It's just an empty mailbox.

Is there any way to do a login test, without locking the index files? 
Hence avoiding these warnings/errors?

Thanks.
