[Messaging, JMS & JBossMQ] - JBossMQ becomes dead slow after few minutes
by shantanu
Dear All,
we have jboss 4 installed on our server. We are using persistent mySQL as queue storage.
Recently we have noticed on a consistent load of 10-12 msg/sec the dequeue process starts slowing down (we use OnMessage Event)
Initially the messages are de-queue at around 50msg/sec however as the time passes, the speed slow to 1 messages per 10 second!
finally the dequeue process stop completely. The other thing we noticed that the CPU usage of java process becomes more than 97% and keep on that for hours before crashing down.
We are not doing many thing in OnMessage trigger. We have also noticed that the issues was non-existence for over 1 year or so. The only recent change has been related to load increased by 10-20% (which is now again decreased to -20%).
We are running jboss on fedora core 1, Celeron 2.4 Ghz processor and 1gb of RAM. Java is running with 128min and 512MB max RAM. We have also noticed that java process never uses more than 233MB of RAM.
Other than jboss we have MySQL 4.1 installed on the same machine. MySQL never take more than 5% of CPU with 33MB of RAM.
regards

[JBoss Eclipse IDE (users)] - JBoss Tools to provide good documentation and jars needed
by pshankar
The Jboss tools project is worst the first visit. The project never tells where do the simple update from
Say 1) Configure ... in Eclipse installer
2) Download the Zip file or rest
3) Get with JBoss IDE(Say you give or not)
Your eclipse update site installation is a big Zero. Missing and update site won't work. Zip files won't show the features in eclipse.
Your JBoss IDE update for eclipse never show hibernate.
Something fundamentally wrong.
The documents are out of sync with the features.
The document never tells where to get hypersonic driver, where to start and nothing is in it. Assume a start tutorial with the driver jars which don't exist or come with hibernate.
On the whole there the process is badly broken. You should have a feedback site for each page to see how the contents are.
Website is unorganized and not good at all.
It is messy than before. I don't know what commercial motive is behind. Buy premium support model for a simple configuration.
