Hi,

on my Linux testbox SLES10 SP2 64Bit (python-2.4.2-18.13), I get the following 
error.
gmond 3.1.0.1527
# gmond -m
[...]
dev-rootvg-usr-disk_used        Used disk space (module python_module)
swap_free       Amount of available swap memory (module mem_module)
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib64/python2.4/threading.py", line 442, in __bootstrap
    self.run()
  File "/usr/lib64/ganglia/python_modules/tcpconn.py", line 260, in run
    self.popenChild.wait()
  File "/usr/lib64/python2.4/popen2.py", line 94, in wait
    pid, sts = os.waitpid(self.pid, 0)
OSError: [Errno 10] No child processes

The problem seems to be an timing problem, as the error occurs only every 
second  or third call of gmond -m. When the error is not shown, gmond -m waits 
some time after the last line swap_free.

Regards,
Ulf
