I did interesting experiment. I runned 2 guacamole clients at the same time on the same vnc server (mirror view in 2 Firefoxes).
1st guacamole client - 0.9.13-RC1 (on docker) 2nd guacamole client - 0.9.12 (outside docker) And acting on 2nd client (outside docker) I was able to hang 1st client (inside docker) by doing "clipboard copy by double click". Contents od clipboards also looks different (see screenshot) Daniel Nguyen W dniu 23.07.2017 o 17:31, Mike Jumper [via Apache Guacamole (incubating) - Users] pisze: > On Sat, Jul 22, 2017 at 3:28 AM, danielos <[hidden email] > </user/SendEmail.jtp?type=node&node=1375&i=0>> wrote: > > > I managed to install gdb in guacd container: > > > > ----------------------------- > > > > [root@480dcc5d723f /]# top > > top - 10:44:32 up 104 days, 23:28, 0 users, load average: 1.66, > 1.95, 1.65 > > Tasks: 4 total, 1 running, 3 sleeping, 0 stopped, 0 zombie > > %Cpu(s): 4.7 us, 0.7 sy, 0.0 ni, 93.8 id, 0.8 wa, 0.0 hi, 0.0 > si, 0.0 > > st > > KiB Mem : 32714444 total, 4350124 free, 4299328 used, 24064992 > buff/cache > > KiB Swap: 1048572 total, 993004 free, 55568 used. 27710752 > avail Mem > > > > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ > COMMAND > > 32 root 20 0 495456 45820 9360 S 100.0 0.1 132:28.00 > guacd > > 1 root 20 0 295568 15732 5332 S 0.0 0.0 0:01.08 guacd > > 39 root 20 0 11880 2996 2584 S 0.0 0.0 0:00.00 bash > > 178 root 20 0 52004 3888 3308 R 0.0 0.0 0:00.00 top > > > > ----------------------------- > > > > > > [root@480dcc5d723f /]# gdb -batch -ex bt -p 32 > > [New LWP 38] > > [New LWP 36] > > [Thread debugging using libthread_db enabled] > > Using host libthread_db library "/lib64/libthread_db.so.1". > > 0x00007f328ab93ef7 in pthread_join () from /lib64/libpthread.so.0 > > #0 0x00007f328ab93ef7 in pthread_join () from /lib64/libpthread.so.0 > > #1 0x00007f32820aa859 in guac_vnc_client_free_handler > > (client=0x7f327c00abc0) at client.c:71 > > #2 0x00007f328b554b72 in guac_client_free (client=0x7f327c00abc0) at > > client.c:193 > > #3 0x0000000000404310 in guacd_exec_proc (protocol=0x7f327c002b63 > "vnc", > > proc=0x7f327c00aba0) at proc.c:191 > > #4 guacd_create_proc (protocol=protocol@entry=0x7f327c002b63 "vnc") at > > proc.c:253 > > #5 0x0000000000403a80 in guacd_route_connection > (socket=0x7f327c00ad10, > > map=0x7f328bacd010) at connection.c:299 > > #6 guacd_connection_thread (data=0x251e450) at connection.c:394 > > #7 0x00007f328ab92dc5 in start_thread () from /lib64/libpthread.so.0 > > #8 0x00007f3289b6173d in clone () from /lib64/libc.so.6 > > [root@480dcc5d723f /]# > > > > guacd and its per-connection processes use multiple threads, so this > backtrace does not necessarily represent where things are spinning. > Rather than just running "bt", please try "thread apply all bt".
