I have a JBoss Server configured with 1Gb availabe for JBoss. I was wondering if someone could make some recommendations about the settings for HighMemoryMark and MaxMemoryMark. At present these are at the 50 & 60Mb resepectivly - but it seems that we should be increasing these to aprox 700 and 800. Does this make sense?
During normal operations our server sits on 590Mb - during peak loads it gets up to 1Gb.
What the OS reports and what the JVM reports as memory in use is slightly different, just so you know. The numbers seem reasonable to me, but I would test by enqueing as many messages as possible and see what the CacheManager does with them.
