Error of a call of procedure through WSA if broker restarted

Hi!

After broker restarted - wsa servlet (hosted at Tomcat) in faulted state. Can't invoke any procedure - throw an exception.
But! if call procedure again - normal work is restored and all next procedure calling do without errors.

This situation - only after broker restarted.

Restart broker:
asbman -i brokername -stop
asbman -i brokername -start

How to solve this problem? Is it real error in wsa servlet or require calling procedure twice on errors it's normal sutiation?
