Subject OutOfMemory issue with Axiom
Date Fri, 27 Nov 2015 05:41:51 GMT
Hi,

I am using axiom-api-1.2.14.jar and axiom-impl-1.2.14.jar.
My SOAP response returns List<String> whose size is 150. Each string having size of
1.8 mb(avg).
When such huge data returns to axiom stax parsing, It suddenly increase the the heap memory
by 600 mb which continued to reatain and not gets relaesed.
When I analyse this in visualvm I found that OMTextImpl class is taking this memory alone.
For the next hit this size increase to 1200mb and again this memory does not get freed.

For next 2-3 hits , system goes to OutOfMemory.

I am using below configuration:
#messageFactory (axiom) configuration
messageFactory.payloadCaching=true


When I use  messageFactory.payloadCaching=false        (I don't know whether this will solve
the problem or not)
I face below exception:
23:21:19.467   [http-bio-8080-exec-1] ERROR o.a.c.s.spi.TransactionErrorHandler - Failed delivery
