java - GWT and an unreproducable 503 error -

-


have web-application built gwt (2.0.3) , run on apache tomcat 6.
application uses long polling enable client-server conversations. when client unable connect server displays disconnected message on page , grays out controls until able resume conversation server.
happens through use of onfailure method of rpc services; keep track on how many consequtive exceptions i've received , if passes defined threshhold above scenario happens.
allows notifying user of problem while in background continuing resume server conversation.
has been configuration 6 months, , without problem.
compiled application after change , wanted see in stand-alone mode started tomcat (not via eclipse) , seemed work fine.
when ctrl+c'd apache (while having clients up) saw clients displaying 503 error instead of app disconnected message.
tried reproduce issue unable next times app behaved expected.
i'm not sure if it's relevant added uncaughtexceptionhandler module's onmoduleload.

has encountered such issue?
know how can make client immune such issue?

thanks lot,
ittai

probably app tried connect server while in process of shutting down. of services might have shut request failed internal server error.
