Hi Rafael,
Our testing has shown that multi does use more resources for the same
throughput; more cpu, ram and storage, but not significantly more unless
you are already at the limit.
We have configured one-kaha-per-queue so it does improve the storage
reclaim when for whatever reason the reclaim
After a while of using the ActiveMQ with mKahadb it crashes with the
following errors:

As suggested by Mark Johnson I'm evaluating a multi-kahadb setup:
But, after that, I'm facing the following warning:

Hi Rafael,
Building on the reply from Marco, we have experienced the same issue with
queues and are evaluating a multi kahadb set up of a kahadb per queue.
Obviously this does increase the total number of files but so far we have
not seen any significant increase in total storage compared to a sin
Hello Marco,
First of All, Thanks for your reply and detailed explanation.
To avoid increasing the KahaDB with DLQ queues, we disable the DLQ, so
expired messages will be discarded automatically:
Because of that configuration, I assume that the problems fall on durable
topics.
As we know th
Hi Rafael,
I’m just an ActiveMQ classic user.
I will report the behavior of ActiveMQ I experienced.
As far as I know the ActiveMQ classic journal is composed of append only
files.
Each file should be by default 32MB in size (this can be changed, I think
is controlled by journalLogFileSize)
A jour
I would add that if you have a maintenance window available - a v. low
traffic time of day or week - where there are typically no persisted
messages, it is going to be least disruptive to use that time window to
perform an upgrade.
Copying across the store might not be necessary, in which case you

We are having similar issues. Did you ultimately delete the old log files?
Or were you able to somehow close the loop on the old transactions.
After running for 3 months, we have 3 old logs that won't die on one of our

Forgive me, but having read this, I'll certainly turn on the trace logging and
investigate, but this document doesn't really say anything about what to
actually DO about them, once you've figured out why they are still around.
Is there more I should be reading?
