Yes, I had reviewed that document, but I are not sure of the reason for the crash is the same. So, I would like further details about the bug, to be sure it's the same case.

Thanks

The server is a rp7440. I didn't capture console messages.

How I could capture old messages in the console via MP?

Thanks,

Hi Roger,

You can run the following command in MP Main Menu to get the console log:

MP MAIN MENU:
CO: Console
VFP: Virtual Front Panel
CM: Command Menu
CL: Console Logs<<<<<<<<<<<<<<<<<
SL: Show Event Logs
HE: Main Menu Help
X: Exit Connection

CL (Console Log) View the history of the console output
CL displays up to 60 KB of console data (about 60 pages of display in text mode) sent from the
system to the console path and stored for later analysis.
