My normal shell-file-name is sh.exe and the shell-command-switch is "-cf". I don't know how to tell the version of cygwin. I often run cygwin setup and it updates whatever it wants to. I seem to have run it last on Dec 25. My setup.exe is dated Jul 13, 2009 and my cygwin1.dll has the date of Jun 12, 2008. -- In any case, I might have made some progress in diagnosing the problem. I got an inkling that the size of the message being piped was a factor. So, I sorted by mbox by size and did a binary search. For a message of size 61682 bytes, it worked. For size 63940, it hung. So, it looks like 64K minus some delta hangs. It could be some buffering issue. I also tried piping multiple small messages. - Three message sized 32, 33, 45: worked. - Four messages sized 32, 33, 45, 53: hung. - Three messages sized 33, 45, 53: hung - Two messages sized 45, 53: worked. - Three messages sized 53, 67, 68: worked. - Four messages sized 53, 67, 68, 72: hung. I don't see a pattern here. Good luck finding the problem. Asynchronous problems are really hard to debug! Cheers, Uday
