I had the same issue a while back. I did the following fixing the issue.
I followed the
following forum to have the sockets increased - http://stackoverflow.com/questions/24179552/insufficient-winsock-resources?rq=1
We have set the
following registry values:
Unfortunately, I could never determine exactly what caused it. You have rebooted I take it ?
Had this issue forwarded to SW Support and this is what they found out.
System.InsufficientMemoryException: Insufficient winsock resources available to complete socket connection initiation. ---> System.Net.Sockets.SocketException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
Possible causes are:
1. OS runs out of memory for TCP buffers
2. OS runs out of available TCP “ephemeral” ports
Did the recommended similar solution from this KB https://support.microsoft.com/en-ph/kb/196271 .
Currently having an issue where the alert page goes blank tabs some of the menu items start to fail intermittently. Restarting SolarWinds services does not work.
Support increased the socket buffer size and stated this was the cause of the issue and is the permanent fix. Previously they asked to patch using a hotfix but that did not work. I am concerned that this recent fix won't solve the issue. Has anyone has this issue?
any idea on what can be monitored in perfmon to capture winsock memory bottlenecks?
have you checked into KB articles. a few say something about expanding your maxTCPPorts or something which the OS natively restricts out of the box, this registry fix permitting you to expand the resources available.
