[haung]

Context

os : centos 3.10.0
version : 3.3.3
I want to use supervisor start a program, use the command directly successed, but use supervisor failed.
thank you very much for any help
program:

[program:agent]
command= xvfb-run /home/chrome
autostart=true
startsecs=3
startretries=3
stopsignal=QUIT
stdout_logfile=agent_out.log
stdout_logfile_maxbytes=20MB
stdout_logfile_backups=10
log:

/bin/xvfb-run: line 186 kill: (32284) - no such process
/bin/xvfb-run: line181: 32338 DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1
/bin/xvfb-run: line 186 kill: (32335) - no such process
But I start the program with the command directly , the process could be started.
log:

[538:538:0929/164549:ERROR:gl_surface_glx.cc(403)] glxQueryVersion failed
[538:538:0929/164549:ERROR:gl_initializer_x11.cc(130)] GLSurfaceGLX::InitializeOneOff failed.

[493:518:0929/164549:ERROR:browser_gpu_channel_host_factory.cc(113)] Failed to launch GPU process.
Although there were some errors in the log, the program really started and worked
I confuse about it that why supervisor cant't start the program. the content in the log affect it
