Hi Gary,

I'm using VisualVM to monitor my application. I am taking Thread dumps to see 
where my threads are Blocked. I can also take Heap dump to see what eats my 
memory. But, I don't understand how to analyze this issue by seeing the memory 
as my application has cache that eats more memory. Any input like the classes' 
instances to be looked for will be helpful.

Thanks in advance,

With Regards,
R Kaja Mohideen

How about using a profiler to see if you have a memory retention bug?

What do you mean by releasing cached information?

I have only javax.xml.transform.Templates cached and the newTransformers are 
created in method scope of threads and those references are not maintained 
anywhere.

Ok.. I forgot to add one important information. My application was running 
smoothly for any number of transformations without any issues previously. I'm 
facing this issue only after I have included EHCache library in my application 
to store the XSLT output. Have any idea where these two conflicts?

Hitting the swapper knee, I suspect.

Yes, it's the user's responsibility to release cached information, when it's no 
longer needed, by discarding the Transformer.
