---------------------------------------
Hi,
Today I checked the status of kahadb files. It contains a db-794.log file
having 32 mb, db.redo file having 1.1 mb and db.data having a big 5 GB.
Why is this db.store file having such a huge size. is there any chance to have
this to cause the above issue. if it is so can i expect it to solved in 5.5.1
version.
Another thing is about db-794.log file. As per Normally log rotation, the
latest file will be a non numbered file. But in this case i can only see
db-794.log. If it is logging only non consumed messages then it seems ok.
Any way we are planning to upgrade activemq vesion to 5.5.1 in production.
