how to configure heap size for jswat - java.lang.OutOfMemoryError: Java heap space

[Kun Luo]

I am using jswat 2003.1 on linux and I keep getting the outofmem error when I ran the jswat program:

 

bash-4.1$ ./JSwat --jdkhome /files/tools/jdk1.7.0_25

java.lang.OutOfMemoryError: Java heap space
Dumping heap to .jswat/setting/var/log/heapdump.hprof ...
Heap dump file created [76803235 bytes in 1.299 secs]

 

Anyone knows how I could configure the heap size and memory size for JSwat?

Hi Kun

Sorry you are running into this problem, it looks like the default maximum heap size is a touch on the low side. You can change this in the etc/JSwat.conf file by modifying the "default_options" setting. Change the -J-Xmx64m part to something like -J-Xmx256m, or even higher if need be. You can also set the jdkhome in that file as well, just uncomment the line and copy the path there.

Thanks
