4942f89a UNSPECIFIED_MARSHAL_25

Explanation
 This error can occur at the server side while
the server is reading a request, or at the client side while the client
is reading a reply. Possible causes are that the data on the wire
is corrupted, or the server and client ORB are not communicating correctly.
Communication problems can caused when one of the ORBs has an incompatibility
or bug that prevents it from conforming to specifications.

User response
 Check whether the IIOP levels and CORBA versions
of the client and server are compatible. Try disabling fragmentation
(set com.ibm.CORBA.FragmentationSize to zero) to determine whether
it is a fragmentation problem. In this case, analysis of CommTraces
(com.ibm.CORBA.CommTrace) might give extra information.
