I've noticed an ocasional problem while running in X11 mode. Ocassionally
nano-X hangs after I press the break key. When it hangs it starts sucking
up about 97% of my CPU (according to "top -s").
Until tonight I've always seen this when running nano-X and an application
seperately. The last few days I've been running with my application linked
to the nano-X library. And I just noticed the problem with the two pieces
linked together. So I guess it doesn't have anything to do with the
client/server socket interface.
I'm not too good with GDB yet, but I was able to attach to the running
process and get a stack trace. Here's what I saw...
.. my apps functions ...
GrMainLoop()
GrGetNextEvent()
GrGetNextEventTimeout()
GsSelect()
GsCheckMouseEvent()
GdReadMouse()
X11_Read()
XCheckMaskEvent()
_XEventsQueued()
_X11TransBytesReadable()
??()
__ioctl()
I didn't have much luck stepping through anything. I didn't have
Microwindows built with debugging enabled tonight.
Does anybody have any ideas on this one?
Thanks,
Gary James
