high memory consumption

Leonardo Pereira
I have a Guacamole server with version 1.1.0. It had been using for three
months, and out of nowhere the server started to consume a lot of memory.
Checking the top or smem and the guacd processes is what consumes the
machine's memory until it overflows. When the memory and swap runs out, the
operating system kills some guacd processes, bringing down some users.


apachegatwayrpds kernel: [ 4945.817132] Out of memory: Kill process 20899
(guacd) score 165 or sacrifice child


Any suggestion?

Are you familiar at all with valgrind?  If so, could you get a report out of valgrind that tracks the memory consumption?  It should be able to identify any leaks.

Also, can you advise on what display protocol you're using for the remote server, and if you're using any non-default options (file transfer or SFTP, etc.)?

Re: high memory consumption

dfk1976
i once had also such raising memory issues too. as i can remember what i did
was to set something like this in /etc/default/tomcat9 and reboot, then the
issues has gone:

JAVA_OPTS="-Djava.awt.headless=true -XX:+UseG1GC"

but this is not sure if this solves your issue.

1) Are you able to test against FreeRDP 2.0.0 to see if this is an issue? I'm starting to suspect that changes in the 2.1.1 release introduced a memory leak or changed the way memory is freed such that a memory leak appeared. There is some precedent for unexpected changes in memory management between versions of the library: https://issues.apache.org/jira/browse/GUACAMOLE-935

2) Do you have debug symbols installed for FreeRDP and its dependencies? Some of those stack traces lack information about the specific functions, files, and line numbers involved on the FreeRDP side. That information will likely be needed to determine exactly what is happening.
