I have a webservice on weblogic7.0 which gets called by some 100 clients every minute (approx). The server has 1GB of physcial memory. It is in Production Mode. The server runs out of memory every single day.
Let me know what your thoughts are on this.
I think you need more memory.
Try tuning your JVM memory and garbage collection settings.
Try for example:
-Xms512m -Xmx512m -XX:NewSize=128m -XX:MaxNewSize=128m -XX:SurvivorRatio=10
Use a profiler to find the memory problems.
