"JBOSS WS | OutOfMemory GC overhead limit exceeded" To view the discussion, visit: https://community.jboss.org/message/726901#726901 -------------------------------------------------------------- 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 -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/726901#726901] Start a new discussion in JBoss Web Services at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2044]
