But also if it is taking an hour before you run out of memory then it sounds as if you may have a memory leak - there is a profiler plugin available for netbeans 4.1 which is quite handy for tracing these - I don't think its on the netbeans update centre but you should find it if you search on the net. Its free.

Two threads run throughout the program, where one is an endless thread. I use JDBC onnection with MySql. An hour after the program has been run, it gives an OutOfMemoryError - and hence the servlet is not called and hence CallForwarding is not set. But again randomly, it works but at other times sends an OutOfMemoryError. On the start of the program, I check the Runtime.getRuntime().totalMemory() --> arnd 1.9 MB Runtime.getRuntime().maxMemory() --> arnd 64 MB Runtime.getRuntime().freeMemory() --> arnd 1.4MB After the totalMemory reaches 64 MB, and freeMemory is less than 34556 bytes, the java.lang.OutOfMemoryError is thrown. Since I am completely new to both JAVA and tomcat, I would like to know how I need to proceed. I believe I must increase the maxMemory -- but how and where? I start Tomcat5 using /etc/init.d/tomcat5 start . I run the JAVA program using Netbeans IDE 4.1 and not via command line. I read somewhere that the option -Xms128m -Xmx256m should be set for JAVA_OPTS environment variable in the startup script used to starting tomcat. But I dont seem to understand where I can add this value in /etc/init.d/tomcat5 file. Kindly guide me further. Any help appreciated.
