Sniffer cannot connect to UNIX S-TAP

Symptoms

When you specify a different number of threads, such as 20, by using the command snif -t 20, the sniffer cannot connect to the UNIX S-TAP. In the GUI console, the status of the S-TAP is inactive.

Causes

The sniffer starts with six threads by default. When the number of threads exceeds the limitation, the sniffer cannot connect to the UNIX S-TAP because of undefined behavior.

Environment

UNIX S-TAP is affected.

Resolving the problem

Reduce the number of threads to make sure that the connection can be established successfully.
