I have 2 users that are using a windows 7 and windows 8 machine and they connect using the anyconnect client version 3.1.05170. They are able to connect without any issues and access their environment but they are both receiving strange errors in their event log about every 30 minutes with this description:
"SOCKETTRANSPORT_ERROR_TRANSPORT_SHUTDOWN:The socket was shutdown by the operating system on a remote peer. callback"
I cannot seem to find any information on this error anywhere. They were previously on an earlier version of the anyconnect and were getting the same errors, we upgraded them hoping it would resolve the issue. This is on a 5515 code version 8.6.1(2). Any feedback would be much appreciated! Thanks
