Issue with corrupted mailboxes and imapd -s connections

We had a server crash and have some mailboxes with corruption issues.
We are running reconstructs on those mailboxes but unfortunately they
have a lot of messages and are taking a long time so we have the mail
server running and are telling our users not to access those mailboxes.
The issue is when they do the connection gets created and that imapd -s
process never dies even though the connection to the folder doesn't
work. I have been individually killing them off myself but is there
anyway to set some sort of timeout on these processes so that these
processes eventually die? Currently they are just churning and using a
lot of memory and taking connections as we have limited the amount of
connections based on memory constraints.
If you need more information from me please let me know...thanks...
This is the error we see in the maillog:
Sep 21 09:30:46 mailserver imaps: imaps TLS negotiation failed:
Sep 21 09:30:46 mailserver imaps: Fatal error:
I scrubbed the connection details. Thanks...
