Did you kill it with kill -9 or not ? Also the bug looks really scary and is a blocker. Maybe we should switch to amq message store for now. I think the risk of a currupt queue is just to high with kahadb atm. I hope the activemq guys will backport the fix it and release 5.4.2 ASAP. Here are the docs for amq message store: http://activemq.apache.org/amq-message-store.html > To solve it, I had to remove the activemq-data directory (btw, 2 weeks ago > was activemq 5.4.0 with 2 brokers started and activemq-data in bin > directory). > > I made a test to restart from scratch my account in thunderbird, and it was > OK. > > Is it because it does a incremental sync and I select different folders > (just to make things complicated :) ) during the download ? > > Anyway, it is not easy to reproduce. > Activemq 5.4.1. may be worth to try, but I'm not sure it the the cause... Well in the jira they say that its only fixed in 5.5.0-SNAPSHOT for now. Hopefully they will back port it. > > Tks, > > Eric > > Anyway I'm 100 % sure the problem with IMAP has nothing todo with activemq.
