[61:3002]Invalid format of the message "MSG_MEDIUM", received from MMA

Dear all, I'm trying to replicate a large Oracle DB (9.5 TB) from one StoreOnce to the other.

The Cell Server (redhat) has DP Version 10.91, the client 10.50. The client is also the gateway on both SO.

Everything is going well, all files where replicated but in the end I get this error and the replication hangs...:

[61:3002] Invalid format of the message "MSG_MEDIUM", received from MMA

Attached the whole replication session...

Hope, someone has an idea

Thanks in advance, Rolf
