Hi,
One our customers reported that their R77.30 device has Operating System coredumps related to "login.tcl" but I failed to find on the Internet similar reports about coredumps.
The file is located at /web/cgi-bin2/login.tcl and is related to web access to the device.
CP SK101967 refers to "Forbidden. You don't have permission to access /cgi-bin/login.tcl on this server" error when connecting to Gaia Portal but there is no mention about other side effects.
Have you encountered similar issues?
