Sending many messages causes lock?

tesuji Jan 7, 2004 7:40 AM

I've been experiencing problems with sending messages through JMS. I don't use any message-beans, simply the JMS API.

First I was seeing problems that the JBoss server would freeze after some time. This seemed to have been caused by not closing the topic/subscriptions properly (which in turn was caused by users killing my application instead of closing it properly). I was surprised to see that improper behaviour of the client caused the server to have problems.

Even when my clients now close the subscriptions properly, I still have problems. I have between 10 and 20 subscribers to a topic. When I publish a single message every now and then all is fine. When I send a dozen messages in a row however, sometimes my receiving clients lock. I can reproduce this in a test environment consistently.

Does anyone have any idea why this happens? I see no errors or exceptions that give me any clue. I tried experimenting with different connection-factories but it didn't make any difference.

Any help would be greatly appreciated.

Post your version information and a threaddump.

It seems we're still using version 3.0.3
In another thread you recommended using 3.0.8 because 3.0.3 had memory leaks. This may explain why we're having problems with messaging. How about the 3.2.3 version I see on the download page? Would you recommend using 3.2.3 over 3.0.8 or not? It's not clear to me what the difference is except that it seems much more recent.

3.2.3 is the current production release.

The 3.0 version is now only maintained for important fixes.
