I'd be interested if you do the backtrace on several of the other core files how many of them are in similar places and how many are different? Things crashing in random places, in my experience, indicates hardware errors, but that may not be the case, since these are in very similar/close places. > > Most of the time it happens when user scrolls any page inside the rdp. > I assume when you say "scrolls any page" you mean using their keyboard to scroll and not the scroll wheel on a mouse? > > Has anyone also got the same ? > I've not seen this at all, and I use several versions of Guacamole (0.9.14, 1.0.0, and various git versions). What RDP server are you connecting to? Looks like you're running EL7 (CentOS or RHEL) - do you have the stock version of FreeRDP installed (1.0.2)? -Nick >

I'm tempted to make it its own protocol, since it seems to be different enough from regular telnet, but it could probably go either way. If you're not up to programming in C, that's fine - no pressure at all - I'll be looking at it when I get a chance, too, and will probably need some help testing along the way.

GUACD CRASHES on KEY EVENTS
Hi Team,
I was continuosly getting the disconnects therefore I have added the below
code to analyze the crashes.
guacamole-server version : 1.0.0
guacamole-cleint version : 1.0.0
Browser : Chrome, Version : 75.0.3770.142
*CODE ADDED IN DAEMON.C*
void setCoreFileLimits()

Apart from this I haven't changed anything in the code.
There are lot of core files generated which is as follows : -
