Data Movement Service - InstanceAlreadyExists

[dropkickmurphy]

Anyone ever come across this error by any chance? We get this only on our standby Content Manager box that has Data Manager installed.

We are having all sorts of issues with Data Manager from the socket server crashing, not being able to communicate with it via soap etc. Any help would be appreciated.

Thanks!

From what I understand this error is typically thrown when the MBean server tries to register an object that is already registered. We are running cognos 8.3 with one web server, 2 app servers all running Red Hat Enterprise.

Thx
