Both top and ps show the process to be monotonically increasing in size. I used Optimizeit to try and isolate the leaks, but although it indicates that Strings and char[] are being leaked, it can't help isolate the culprits. Also, the size and amount of leaks indicated by OptimizeIt are miniscule compared to the number reported by top or ps.
I'd appreciate it if the experts could look at the short program that I have attached and see if ther is anything I'm doing incorrectly.
I have attached my.java - which is the program, PASSEngineConfigurationFactory.java - to use commons httpclient, o - the shell used to start the java program.

Hi Fredo,
Maybe it is a problem with your JVM?

I'm using axis as a ws client and I get a memory leak everytime I send a
request. The requests and responses are very small (less than 500 bytes),
but the memory leak is significant. I'm using java 1.4.1 on Solaris.
I was using axis 1.2 snapshot from Jan 6 2004 that I compiled. I re-compiled
with the snapshot from March 24 2004 (last night) and have the same type of
leak.
I read the email archives and found that others had complained about memory
leaks as well, but there was no acknowledgement/resolution posted.
So, does anybody have any insight into the memory leak problem with axis?
