For example, the operation 'ps -el' completes almost instantaneously. Yet seemingly randomly the operation 'ps -el | grep ' often takes 30 seconds -- actually it seems to either return instantaneously or take 30 seconds. It doesn't seem to make a difference whether the actually occurs in the output of 'ps -el' In particular, I initially found the problem with =rsync But it seems to happen with reasonable frequency with many other strings. However, it is not reliably repeatable... Any idea what may be wrong here? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
