I have turned tracing on. I can't read it fast enough before 24x7 dies.
I can ping by name, but not by IP. Using DOS, I can ping using both. Pinging by IP in 24x7 causes it to crash, no diagnostic messages.

The script is straightforward.

Dim isRunning, boolean
Ping( 127.0.0.1, isRunning )
MessageBox( isRunning )

There is a problem in your script. Please change it to the following.

Dim isRunning, boolean
Ping( "127.0.0.1", isRunning )
MessageBox( isRunning )

The original crash occurs because 24x7 attempt to treat 127.0.0.1 as a decimal number while it is not a number.
