RE: [rules-users] memory issue when listening to market data

It's Linux 2.6.9-42.0.10.ELsmp, with Sun jdk1.5.0_08. If top is not reliable, how should I detect if there is any native memory leak? Thanks. -Ping ________________________________ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Augusto Rodriguez Sent: Monday, September 29, 2008 11:40 AM To: Rules Users List Subject: Re: [rules-users] memory issue when listening to market data Hi Ping, Which OS are you using? Because top doesn't work very well in all OSs (for example solaris). Cheers, Augusto Cheng, Ping wrote: All, I wrote a server which listens to the market data and generates alerts based on some conditions. It listens to about 300 symbols and contains 30 simple rules. It works fine when the market is quiet. It uses about 500 M in memory and there is no big difference between reports from top and jconsole. When market is busy, memory displayed in jconsole is still ok, but top reports much more memory and it did not come down at all. Sometimes it could reach 50G when it's a crazy day. I used jmap to check the memory map and it looks fine from java view, I wonder if drools hold something when it's very busy? What is supposed to happen if drools could not handle the work load?
