Symptom

Operating system call WSASend failed (error no. 10053) entries are appearing in the Syslog (transaction SM21) periodically, triggered by the user SMDAGENT_<SID>.

Note: SMDAGENT_<SID> user is the key point to check whether this KBA is relevant or not. For other users, it may be caused by other reasons.

The following (or similar) error can be seen in the corresponding work process trace file (dev_w*) in the work directory (LocalDrive\usr\sap\<SID>\SCS<XX>\work):

M ***LOG Q0I=> NiIWrite: P=127.0.0.1:3300; L=127.0.0.1:<port>: WSASend (10053: WSAECONNABORTED: Software caused connection abort) [nixxi.cpp 4615]
M *** ERROR => NiIWrite: SiSendV failed for hdl 16/sock 2036

In the level 2 Gateway trace file (dev_rd), it can be seen that the Gateway closed the connection due to idle monitoring timeout:
