Hi,

in the latest weeks i'm working on the Solr integration and immediately i've faced the assertion failure errors, on 2.0.19, 2.2.9 and 2.3.11.3 servers in our network.

Reading the thread on debian ML, I realize this issue is related to nested MIME and it affects large mailboxes

In my case, the error in dovecot.log pairs with the following on solr.log and it seems the rows value has the same value of the last UID recorded in the mailbox.

For your reference, here is the Solr logs, where 2276996170 is the value passed by Dovecot as rows number and it clearly don't fit with the rows data type.

Have you had experienced the same behaviour? Is there a workaround?

Thanks

Antonino
