s - processes and applications stopped responding and other things on my system just before. When I went to use xkill from a terminal it shown me the problem...
[x11@kintaro nicotine-1.0.8]$ xkill
bash: fork: Resource temporarily unavailable
I then got an error like this from another program that stopped responding...
Traceback (most recent call last):
  File "/home/x11/dev/nicotine-1.0.8/pynicotine/gtkgui/frame.py", line
308, in OnNetworkEvent
    self.np.events[i.__class__](i)

    timer.start()
  File "/usr/lib/python2.3/threading.py", line 410, in start
    _start_new_thread(self.__bootstrap, ())
thread.error: can't start new thread
Anyone have any ideas what would cause an error like this?
