A project we are working on has serious problems.
We are using ND 4.1.3 SVP1 under Windows NT with SQL-Server 6.5
The clients are java-applets.
Almost everyday the ND-Server goes down. One service after another goes in the
red state.
Before this happens, the logfile shows numerous similar CORBA errors:
CPService-Thread-4 Thread-4 .netdyn.services.dsrdbms.client.CNdDSRdbmsProxy Thread-4
egetWorker: systemException: org.omg.CORBA.MARSHAL[completed=MAYBE,

jgetWorker: systemException: org.omg.CORBA.COMM_FAILURE[completed=MAYBE,

or even stranger

�Proxy: bogus worker in reservation context org.omg.CORBA.MARSHAL[completed=MAYBE,

This looks like the synchronisation of corba-objects is broken, because
the MAGIC_NUMBER is identical for all corba messages. So a
wrong MAGIC NUMBER should never appear. An invalid message should also never
appear
Is this a bug in the ORB Visibroker?
Did we configure something wrong?
Does this come from a bug in our code?
Do we have a faulty TCP/IP-Stack
If someone faced the same problem, please let me know. My customer is very upset
about this happening over and over again and we don't have a clue what we are doing
wrong.
If you need more of the log, please let me know.
