Hello,
I am stress testing a minifilter on Win7. Under high-stress conditions FltSendMessage returns an NTSTATUS of STATUS_PORT_DISCONNECTED (0xC0000037). FltSendMessage seems to work fine under non-stress conditions. Can anyone tell me how to either recover from this condition (and reestablish communications to the user mode app) or avoid this condition in the first place. Any and all suggestions are appreciated! Thanks.
