RE: HELP Req: JMeter closes abruptly ...

[Niket Redkar <ni...@dishatech.com>]

Thanks Mark, Sebb, Deepa, Daniel, and Kiran for your quick replies and
helpful suggestions. 

I think your solutions have worked. I executed the script on a small scale
and it did not fail where it used to. 

As per Deepa's suggestions I added the extra parameter "-Xincgc" in the
JMeter Batch file. I think this extra parameter invokes Java Garbage
Collector explicitly. 

Deepa, please correct me if I have misunderstood the use of this extra
parameter.

Also as per Mark's and Sebb's suggestion I removed the "asserts" that I have
been using. That increased the performance of JMeter and it started firing
more frequent requests. I am going to execute the full test tonight and
hoping to see good results tomorrow. :-)

Thanks very much everyone !

- Niket

I had a similar problem.  The issue for me is in debugging my script I left
a assertion listener in it.  Which was logging everything.  This is like
having a built in memory leak in your script.  Be sure especially if you are
running long duration tests that you minimize these things

I'm not too sure as I'm not really talking from experience with JMeter 
however I would give it a try and see what happens.
