Couldn't get vsize Issue

Hi All,

Looking for a little help, please.

We're getting the following showing up in our dovecot logs: Debug: Mailbox Junk: Couldn't get vsize from mailbox list index: Record for vsize. This is happening for all(?) the different mailboxes

We're not sure what we're looking at or looking for to even begin the t/shoot. I dropped the above into google but couldn't *seem* to find anything relevant.

Would someone(s) be able to point me in the right direction as to what the actual issue is (ie some more in-depth detail than just the log message - yes, it may be obvious to some but not to me) and, more importantly, what to look at to get it resolved, please.  :-)

Thanks in advance
