My application use openGL to draw some image on window, and modify led
state on keyboard through faking key event. The operations are executed
at 33ms interval.
If I add some system pressure, after long time execution, there is a
rare possibility to occur below two errors.
#1
XIO: fatal IO error 0 (Success ) on X server "-"
after 21 requests (9 known processed) with 0 event remaining.
#2
X Error of failed request: BadLength (poly request too large or
internal Xlib length error)
Major opcode of failed request: 148 (XTEST)
Minor opcode of failed request: 2 (X_XTestFakeInput)
Serial number of failed request: 16
Current serial number in output stream: 20 X Error of failed request:
BadLength (poly request too large or internal Xlib length error)
Major opcode of failed request: 148 (XTEST)
Minor opcode of failed request: 2 (X_XTestFakeInput)
Serial number of failed request: 15
Current serial number in output stream: 20
I didn't find any clue in Xorg.0.log and message log.
The system pressure is, Mem: 40MB free and 500MB swap is used, CPU: 95%,
continuous disk writing, opengl demo(moving gear).
Could you please tell me what may cause these two errors? It's urgent.
Thanks very much.
Best Regards,
Ma Qingyu
