Hi,
We are developing one element management system with its Web Client running
on Tomcat in a solaris box. It was observed that tomcat server process is
getting killed automatically. We checked the log files. The whole sequence
is just like when undeploying the war file, but without anybody actually
performing that. But here the the tomcat process itself is getting killed.
We are using Tomcat version 5.5.12 and JDK 1.4.2_12-b03
H/W details : Sunfire V440 server with dual CPU & 4 GB memory
Log file details:
tomcat.log
