I am considering purchase of JProfiler, OptimizeIt 5.5, or JProbe. Does anyone have
wisdom to share on the features of each? Are there other good profilers I should
consider?
We have been experiencing regular JVM crashes on our production Tomcat 4.1.24
installation. Originally we were running the Sun HotSpot 1.4.1_02 client, then server
(on RH Linux 8.0). Now we've switched to BEA JRockit 8.1 and are still having
crashes, clearly something is bad in our code - or perhaps we need to start
load-balancing. We have tuned obvious kernel parameters like file-max, and have 2GB
physical memory (1GB is given to tomcat's heap), dual Intel processors. Besides a few
small Java-based daemons on the server, it is dedicated to tomcat.
We recently migrated from a Windows 2000/ServletExec 3.1/Sun HotSpot client 1.3.1
environment which didn't have these problems - I'm not sure what to think at this
point.
Please reply directly to me (and cc the list) as I receive only the digest version.
Thanks!
