JVM crash on LSF submit

[imprezka88]

Hi,

I'm getting sometimes (not always) JVM crash while trying to submit a job to LSF using this library. There are different exception stacks sometimes but always same line seams to be problematic:

j com.genestack.cluster.lsf.LSFBatch.submit(Lcom/genestack/cluster/lsf/model/SubmitRequest;)Lcom/genestack/cluster/lsf/model/SubmitReply;+0

Attaching log from 2 crashes. Do you maybe know can cause that? And how to fix it?

hs_err_pid4917.log
hs_err_pid6065.log

As far as I can see, your logs say that SIGSEGV error happens on a call to strlen function:

# Problematic frame:
# C  [libc.so.6+0x16e901]  __strlen_sse2_pminub+0x11

However I do not see any debug information about the actual call stack. Maybe you can try to compile the native code with debug information to get more detailed call stack information.

BTW, while I was looking into the code, I found out that we forgot to release memory for recently added field in SubmitRequest, in #6 . I've fixed this memory leak in #8 , so you might want to try out these changes.
