how to tell if hitting the Centera streaming limit

Hi,

We're trying to stream clips from an old Gen 2 Centera ( running on an old 2.3 OS ). We have 30 servers, each connected to the cluster pool and use 20-25 threads to stream the clips. So there's a total of 600+ threads streaming from the Centera at all time... When we tried to increase the streaming threads, we see quite a lot of FP_SOCKET related errors ( we saw quite a bit of the errors even with current 600+ streaming threads ), errors mostly like:

*******************

        Error Code: [-10101]
        Error String:FP_SOCKET_ERR
        Message: Premature end of packet

Error Stack:Networkpacket::receive(Connection&) ReadBlobTransaction.readBytes(HPPImportData&) er.readBlob

        Error Code: [-10101]
        Error String:FP_SOCKET_ERR
        Message: receive: waitForReadingData(120000) returned zero

**************************************

so the question is:

1) Does that indicate we're hitting the connection/streaming limit of that old Gen2 Centera?

2) or if there something we can tune?

P.S. Clips are opened in FP_OPEN_FLAT mode, and blobs are streamed with FPTag.BlobRead using the Java CenteraSDK latest version.
