Best bet is to open a PMR.

Subject: [EXTERNAL] [WEB400] IWS OutOfMemoryError / Java Heap Space
Date: Mon, Jul 15, 2019 2:40 PM
 
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.
