Martin, That's all interesting, but we're not running Fedora Core 4 -- we are running Fedora Core 3. Secondly, I've got this identical environment running in production without incident. This environment on this server "used" to run without incident until we had to replace the memory, and now it crashes -- same config I've got running fine in other places -- which is why I'm trying to figure out what's different. What I know is different is that this server has 4GB of RAM when all of our other servers have 2GB of RAM, so that is a difference.
Otherwise, they run the same J2sdk1.5.0_03, all run Tomcat 5.0.30, and all run the same version of our application. That's why I was hoping to gain some insight from the PID file that got thrown to see what might be causing the issues -- do you have any suggestions on how to debug this environment to get at the root cause here? thanks, Kim :-) On 7/21/06, Martin Gainty <[EMAIL PROTECTED]> wrote:
Kim- Did you see this catch this bit of legalese in tiny print Fedora Core 4 users are advised not to use the Java RPM provided by Sun. It contains Provides that conflict with names used in packages provided as part of Fedora Core 4. Because of this, Sun Java might disappear from an installed system during package upgrade operations. Fedora Core 4 users should use either the RPM from jpackage.org or manually install the Sun Java tarball into /opt. Sun Java 1.5+ is recommended for stability purposes. And also this .... These packages have been modified in Fedora to remove proprietary software dependencies and to make use of GCJ's ahead-of-time compilation feature Apparently there exists some 'dependency' not only on package naming but another depdenency on their ahead-of-time compiler.. Play it safe download from http://www.city-fan.org/tips/JpackageJava and install the JVM from there..
