Opensshd 2.3.0-1 weird exec problem


Hi, 

 I'm using Opensshd 2.3.0p1 with Cygwin 1.1.6 on a bunch of Win2k
machines. I
run sshd via srvany. I'm seeing a problem when executing remote
commands. Basically, I'll get output from the remote command about 1
in 5 times I run it. The timing appears fairly random, take some
command like,

 ssh root@my_test_box uname -a

and I'll get the expected output about 20% of the time. The frequency
doesn't change with different commands. Everything else works fine- I
can get a shell, scp files, etc, no problem.

 If I run sshd in debug mode, the problem never occurs. 

 The same thing happens on a number of machines. There's nothing very
unusual about the installation- I install the Cygnus provided binaries
as part of an unattended install, I just use the contents of
bootstrap.zip to untar all the packages in /.

 Below is the output of cygcheck, run via "ssh root@my_test_box
cygcheck -s" (thought that might help).
