Howzit Ralf?
I appreciate this thread is pretty cold but we just received this message last night so while investigating I found this thread.
2014-03-11 19.16.28 STC61310 DSNL511I +PB06 DSNLIENO TCP/IP CONVERSATION FAILED 786
786 TO LOCATION ::10.31.32.212
786 IPADDR=::10.31.32.212 PORT=61353
786 SOCKET=SENDMSG RETURN CODE=140 REASON CODE=76697242
We have PTF UK80357 on our systems, which recommends a local fix/work around to avoid the DSNL511I message, application should issue a CAF DISCONNECT which results in an explicit disconnect.
I don't believe this should be happening but I will follow up.
Cheers
Bruce
