Opened Session for "ServerName" repeatedly

The Platform is 6.02 CF2. I have searched the postings but have not found an answer that works

My server continually opens sessions for itself without dropping them until I get “network pool is full” error and the server hangs. It takes about 24hours to get to this state.

I have tried adding the IOCP_Disable_async_notifications=1 line to the notes.ini file but it didnt help at all.

Has anybody found a solution to this?
