Nischay Rathor commented on GUACAMOLE-86:
-----------------------------------------

Hi [~mike.jumper], I tried to collect GDB dump for guacd process as you mentioned. I tried it many times. Refer shared link. Below are my observation.

1. Every time I executed tree / from ui (it dumps approx. 15mb of output to stdout). Guacd crashes in first or second attempt.
2. I observe only 2 traps messages in dmesg.
