Larry,
The issue is that strace output is too voluminous and os too intrusive.
strace itself brings down the performance of the server I built. I tried a
Dec 2001 pckage of cygwin and got the same results, so my guess is that the
problem manifested itself somewhere b/w Dec 2000 and
Dec 2001.
Are there ftp archives of the older packages I can try. Please help me out
here as I have really bad deadlines that I have too meet :)
THanks
-Johnny
