java - Spring RmiExporter service fails after successful startup -

i'm experiencing situation rmi service configured using spring's rmiserviceexporter starting fine, , usable while - after unknown amount of time, service unavailable though java process spring context still running.

at moment work around reboot java process, hardly acceptable in production environment. cannot figure out, or begin guess, why might happening, or might going wrong. no s/o or google search has been useful, because find examples of rmiserviceexporter failing start @ all, not starting ok , failing later on. clue @ useful.

output of lsof | head -1;lsof | grep 1197, before service fails:

command     pid       user   fd      type             device size/off      node name java       6882     ubuntu  176u     ipv6           54677985      0t0       tcp *:1197 (listen) 

service-side spring config:

<bean class="org.springframework.remoting.rmi.rmiserviceexporter">     <property name="servicename" value="myrmiservice" />     <property name="service" ref="myservice" />     <property name="serviceinterface" value="package.myservice" />     <property name="registryport" value="${my.rmi.port}" /> </bean> 

client-side spring config:

<bean id="remoteservice" class="org.springframework.remoting.rmi.rmiproxyfactorybean">     <property name="serviceurl" value="rmi://${my.rmi.host}:${my.rmi.port}/myrmiservice"/>     <property name="serviceinterface" value="package.myservice"/>     <property name="lookupstubonstartup" value="false"/>     <property name="refreshstubonconnectfailure" value="true"/> </bean> 

client-side stacktrace, after service fails (lsof reports nothing):

which web server using ?

if apache tomcat, add catalina_opts variable

-djava.rmi.server.hostname=10.0.34.11 

in catalina.sh file , export catalina_opts variable.
