JBOSS WS | OutOfMemory GC overhead limit exceeded

[kcsavant]

Hi All,

We have a web service deployed on JBoss 5.1.0 GA with JBoss Native 3.2.2.GA . (Got to know that Native WS is EOL now, will work on migration later). We used bottom-up approach and we are sending a complex java object that contains Strings, Long, Boolean and byte[] to web service.

We are calling web service for almost 60 to 90 times per minute. We are getting OOM GC overhead limit exceeded often (every 2 to 3 weeks), we got the heapdump (we have a heap of 1.5G) for that, on analysing the heapdump we see a lot of objects of ConcurrentHashMap for almost 1G. Most of these ConcurrentHashMaps<String, Object> are containing key as pointing to some XSD that is in-turn pointing to the web service class we have, for example the key is java.lang.String "JBossWS_webservice.my_package.my_company.com_8892700084997890448.xsd", here our web service implementation class is in com.my_company.my_package.webservice package. All the ConcurrentHashMap shows same kind of stuff.

Can anybody please advise why there are so much of ConsurrentHashMap object in heap ?

Thanks,

Keshav

Are you also running jaxws clients on the same server?

In any case, I believe this might be something related to jaxb.

I tried the JBoss 5.1.0.GA and JBoss WS 3.4.0 combination, and while profiling it I noticed the object creation is too less and hence the memory consumption. Can I assume that this problem of JBoss WS 3.2.2 GA has been fixed in later versions ?
