We had similar problems. The reason turned out to be a memory leak in the JDBC
drivers we are using. Java's garbage collector could not free some objects
allocated by the JDBC drivers and as a result, Java had to increase its heap
size until the upper limit was reached. Surprisingly, we did not usually get
any "Out of memory" errors or exceptions in the log files.

Maybe you should check for memory leaks too. Run Java with the -verbosegc
option by setting "wrapper.bin.parameters=-verbosegc" in jserv.properties.
