Re: IWS OutOfMemoryError / Java Heap Space

Not sure, but confirm you are setting/initializing all length fields.

If that does not help, post code source that results in a simple recreate

Sent by: "WEB400" <web400-bounces@xxxxxxxxxxxxxxxxxx>

When calling a REST/GET web service on a 7.1 OS machine to a IWS WS
2.6, I'm getting the following response...

Error 500: javax.servlet.ServletException:
java.lang.OutOfMemoryError: Java heap space

The other WS that is a POST works fine. The web service job
contains all kinds messages in the joblog about dumps/snaps from the
JVM. It previously worked on another box but now this odd behavior.
I'm not sure where to start digging.

I bumped up min/max memory in to WS config and restarted the server.
Same results. I'm able to debug and walk thru RPG code in RDI but
when RETURN occurs, the dumps and errors happen.

Other things of possible note.. This get uses a manually doctored
PCML that was necessary because of varchar on 7.1. I believe same
PTFs are applied as previous development server.

Any thoughts would be appreciated.
