NimbostratusSocket error with load
We get the following error when throwing load at the system. Regular VS with tcp and http profiles. Concurrent users were about 250. HIts per second was 1000
Action.c(58): Error -26000: rc=-1/WSAGetLastError=10038 from WSAEventSelect(_nSocketFD=4294967295, _pvEvent=00000000, muiNewDir=0x00000021) in SocketDesc::SetWaitDir for this=06FC7174: An operation was attempted on something that is not a socket.
doc_hack_12696Somehow the earlier post did not come well - here is the error

I assume that is the client's error message. Do you see any errors on LTM when the issue occurs? Specifically in /var/log/ltm?
Which BIG-IP platform are you testing on (1500, 1600, 3600, 3900, etc)? 1000 HTTP requests per second shouldn't put much of a dent on any of the recent platforms. What do the performance graphs show for CPU and memory usage?
Aaron- doc_hack_12696NO errors. We use 2 F5 devices. One at the web (8900) and another at the APP tier (3600). No errors in either one.
