facing issues in Axis

[Umesh Barik <ba...@yahoo.com>]

Hi,
I am trying to develop a Simulator which receives huge records from client. After sometime it throws following exception.

Exception in thread "SIP-Server" java.lang.OutOfMemoryError: Java heap space

Assuming it could be due to low RAM size I specified the max and min JVM memory size with the -Xms and -Xmx parameter. But it did help me. Also after removing the processing of the records into memory, the above exception changed to something as follows:

I don't have any idea at this point of time how to solve this. Any help will be appreciated.
