Hi,
We have a process consuming too much CPU, is in a loop. This process is
launched for other, which is children telnetd. The process owner is not
logged in, now.
But the telnetd conection exists and the status is unknown, cause TCP can't read inpcb at 0x00000000. It appers the socket is lost.
Why is this situation produced? Which does solution exist to not have this situation again?
Any idea? TYA
Here it is the information:
