Hello Matt,
 Good to know. I was starting to scratch my head on that one. Are you setting up a pipeline or are you doing this manually at the moment?

Subject: Re: Memory issue running EvioToLcio on jlab batch
 
I got this to work by removing the -Xmx2048m option and letting java figure things out for itself.

Im trying to convert some evio files  to lcio using the jlab farms but I cant seem to get the memory allocation to work

In the xml submitted to auger I have the 
 <Memory space="2500" unit="MB"/>
and run with 
java -Xmx2048m

(Ive actually tried a bunch of settings, but no luck).  

I get this error:

this works fine running on my mac and interactively on the ifarms, but I think the problem is that were running 32-bit java on the batch machines (as scicomp says we are supposed to) and it has problems with large memory maps.  Anyone have any ideas to get around this?  

Thanks, Matt
