convertd looping on some messages

[bdial]

I did an imapsync migration of a huge shared folder structure last night, around 100,000 messages. Of course there were a lot of errors in mailbox.log about some attachments unable to index. However, while I can read the messages in zimbra, I can't put anything in the folders. If I try, it eventually times out. It appears that there are a lot of messages in /opt/zimbra/convertd/inprocessing and any time I try to put a new message in any of hte folders under this account, it tries to convert/reindex all of those messages first. My questions are

1. can i just remove everything under inprocessing and that should solve it?

2. Most of the attachments it's failing on are types that shouldn't be indexed/converted anyway (engineering drawings) so I'd like to tell zimbra not to try to index those in the future. I saw this thread disable indexing which mentioned problems getting it to not index particular types. Can anyone suggest the proper way to do it in 5.05?

I stopped zimbra, removed everything under /opt/zimbra/convertd/crash and /opt/zimbra/convertd/inprocessing, and restarted zimbra. The account with all the messages is pretty inactive until the minute i try to put any message in there, then it kicks off convertd processes of other messages (not the one i'm putting in). Is there some other spot that convertd is 'queuing' messages to be indexed?

There is some information about disabling indexing on the Wiki at
