我正在使用Xserver在无头模式下运行OpenGL，并多次调用此api：https://github.com/RobotLocomotion/drake/blob/74292cacd1c42d6b3e682dc836254cdb834ea2e6/geometry/render/render_engine_vtk.cc#L311

偶尔但几乎总是有一个

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  61
  Current serial number in output stream:  62

glxinfo：

glxinfo
name of display: :0
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 50 requests (50 known processed) with 0 events remaining.

/var/log/Xorg.0.log日志的最后几行：

有人可以让我知道下一步要在这里调试吗？
