When using a simple TCP/IP server derived from ruby's standard GServer jruby will run out of memory. MRI ruby will not. I could not find any combination of the following java arguments to alleviate the problem:
on my box the +HeapDumpOnOutOfMemoryError will motivate the generation of the hprof file in 6-8 minutes every time. I moved the code to an 8 gig 64 bit windows 7 box. The issue still occurs but takes longer (I do increase the memory amounts).
Launching via jruby or 'java -server -jar .\lib\jars\jruby-complete-188.8.131.52.jar' makes no difference. Only launching via mri ruby resolves the issue.
The issue was originally detected in 1.6.5 and I upgraded jruby to see if the issue went away (It did not).
