Hi,I've put Activiti under some high load and faced problems with DB connections. For first ~minute processing was fine, but later everything freezed just to throw "IJ000453: Unable to get managed connection for java:jboss/activitids" exception 90 secs later.<!–break–>Activiti Engine instance

Yes the DbIdGenerator needs a connection to the database to retrieve the next block of ids. So if there's no connection available anymore it gets blocked. You could use the StrongUuidGenerator instead or increase the number of connections in your pool.
