----------------------------------
Summary: Apparent memory related issues calling getPort
Key: CXF-9103
URL: https://issues.apache.org/jira/browse/CXF-9103
Project: CXF
Issue Type: Bug
Components: WS-* Components
Affects Versions: 3.4.10
Reporter: Mike Douglass
Running a service for many years making batches of SOAP requests to query and
update a system. Recently made updates which required a move to Java17 with
wildfly 26.3
Started getting intermittent exceptions as shown in the stack trace below.
These were only showing up in the deployed prod system - not on the dev system
or my laptop. Eventually discovered it was the heap allocated to the jvm which
triggered it. With a 2G heap after about 40 calls to getPort it failed as below.
The main problem I have with this is that there is no indication what the real
error is and the error message doesn't help. Looking at the code there is some
logging at FINE level - DEBUG might be more useful. Also there are a whole
bunch of possible failures which all get expressed as "Unable to
locate/load..." (Mosytly looked at the code in CatalogXmlSchemaURIResolver and
what it called.)
It's probable the code was making an excesssive number of calls to
getService().getPort(...) (every request). I made changes to only create a
Service object once for each URI and only create the port once. This seems to
have fixed my issue. However, lacking any more detailed messages I've had to
guess at this solution. It also leaves open the possibility that this will fail
in the future if memory gets tight for some other reason.
I'd also note that the garbage collection stats don't seem to reflect any major
problems.
I've seen references in other ssues to WeakReference's - is it possible
something is being removed and causing this issue?
Failed to create service.
