Hi there,
I ran JBoss 306 on JRE1.4.2. I saw JBoss process did full garbage collection every 1 minute, even when there were enough memory. Does JBoss call System.gc() every 1 minute? If so, can I disable it? I prefer let JRE to decide when GC is needed. Here is a GC log from JBoss process.
Any help is greatly appreciated.
