tomcat - OutOfMemoryError Java heap space -

we had production environment on tomcat 5.5 jdk6. last week upgraded system tomcat 7 jdk 7. since getting outofmemoryerror on daily basis.

i added flags capture heap dumps on oom. analyzed them using memory analyzer tool. dumps show suspected object com.sun.org.apache.xml.internal.resolver.catalog shallow size of ~56b , retained size ~1.3 gb following stack traces

i suspect problem occurs because i'm calling webservice.

i using following jvm options minimum memory set 500m , maximum 1500m

-xx:maxpermsize=170m -xx:+cmsclassunloadingenabled -xx:+cmspermgensweepingenabled -xx:+heapdumponoutofmemoryerror -xx:heapdumppath=c:\heaplogs\ 

this sounds similar this bug. if same, catalogmanager holding references every instance of catalogentry ever created. link suggest can reuse same service object you'll have reinitialize each call force catalogmanger give references storing.

another post in thread suggested trying below force catalogmanger give references

-dxml.catalog.staticcatalog=false 

personally i've had luck axis2 consuming soap if above not work.
