IBM Platform Symphony 6.1.0.1 Interim Fix 344644 Readme File

Abstract

The client host retains and uses up remote direct memory access (RDMA) buffers, causing the client to crash.

Description

RDMA buffers are used up and the client does not have enough buffers. This fix introduces a new API class called SoamDataBlock:SoamDataBlock::releaseBuffer, which can actively release buffers for the client, and therefore, prevent the client from crashing.
 
This API behaves as follows: 
1) When buffer data has been sent out, there is no release on the buffer, and it writes information to the API log.
 
2) When buffer data is not sent out, the buffer occupied will be released. After releasing, the buffer returned by SoamDataBlock::buf will no longer be available.
 
This fix is applicable to Linux 64-bit platforms.
