JMS Message Buffer Size
weblogic, 9.2, JMS, performance
When amount of memory occupied by arriving JMS messages (message buffer) reaches a certain level, JMS server starts writing (paging) them to disk. If message buffer size is not specified explicitly, then server uses default size that is derived from the maximum configured heap size. In many cases, especially if you have more then one JMS servers on one weblogic isntance, the default size may be too big. It is recommended to explicitly specify message buffer size for JMS server. Please note that this does not prevent JMS server from accepting new messages, this just allows writing these messages to disk instead of keeping them in memory. Also note, that this does not guarantee against of Out-of-Memory errors, this just allows too reduce their likelyhood. For guarantees use message quotas.

I wonder how many times critical applications went down because of this condition and people never figured out why it happened. I guess we will never know that but now we can prevent that from happening, thx to Alex.
