Hi Gilberto,
I ain't much of a JPA expert but I will try to answer to the best of my
capabilities, hoping it helps you.
I think the EmbeddedActiveMq class creates a default activemq broker
with default storage settings, which must be around 20mb. The attachment
of your user seems slitghly bigger than this limit, filling up the
queue. James keeps crashing then I guess as the message keeps staying in
the queue.
Is the faulty email important to keep or not? If not can try to clear
away the queue. The data of activemq should be inside the container at
/var/store/activemq.
I think you can try to clean what's in
/var/store/activemq/brokers/KahaDB/* (cf
https://github.com/apache/james-project/blob/3.8.x/server/queue/queue-activemq/src/main/java/org/apache/james/queue/activemq/EmbeddedActiveMQ.java)
I guess you could back up the data as well, from /var/store/activemq,
and reinject the data in an external volume with more space that you can
mount then in /var/store/activemq ?
There is unfortunately no configuration for ActiveMQ storage space. The
configuration file would be activemq.properties, but I think it is just
about some metrics configuration so far. But maybe that could be a nice
contribution to propose?
Regarding the migration from 3.8 to 3.9, here there is a file for
upgrade instructions in general:
https://github.com/apache/james-project/blob/master/upgrade-instructions.md#390-version
I must admit people need to figure out which upgrade concerns which
product, if concerned or not, it's not really practical sorry. We got
room for improvement here I think too.
Let me know if this helps you.
Good luck :)
Rene.

Hi Apache James Brain Trust,
I am having issues with my James server. I am running James 3.8, JPA in a
Docker Container. A user was attempting to email a large video file and
that seems to have crashed the server. I get this message in the log file:
[WARN ] o.a.a.b.r.Queue - Usage(Main:store:queue://spool:store)
percentUsage=100%, usage=20779975, limit=20765548,
percentUsageMinDelta=1%;Parent:Usage(Main:store) percentUsage=100%,
usage=20779975, limit=20765548, percentUsageMinDelta=1%: Persistent store
is Full, 100% of 20765548. Stopping producer
(ID:7a04cd6de807-43041-1775136440917-5:2:1:1) to prevent flooding
queue://spool.
I am struggling to figure out how to resolve this issue (I found this link,
but I am unable to figure where the ActiveMQ files are located) (
https://knowledge.informatica.com/s/article/Persistent-store-is-Full-100-of-Stopping-producer-ID-to-prevent-flooding-error-in-DataExchange-logs?language=en_US
).
I would appreciate your help in resolving this issue (restarting the server
has not helped). How do you stop the "producer"?
Also, where can I find the configuration file for ActiveMQ?
I would also like to know how to back up the database files, if that is
possible?
Is there any documentation on how to migrate from 3.8 to 3.9?
I look forward to any feedback.
Best regards,
Gil Espinoza
