In each case, ls fails. Is there any way to determine what would
randomly be killing ls? Symantec AV is the only thing I can think of
that might do it but there's no indication in any of it's logs that
it's taken an action against ls.exe.
I did a quick google search on "virus +ls.exe" and found lots of hits.
There's apparently some malware that creates a file named ls.exe which
is making me even more suspicious that this it's Symantec trapping what
it thinks is a virus. I've configured Symantec to ignore everything
under the c:\cygwin directory but it's still happening. Perhaps a reboot
is in order.
