but I can run bash or linux sh and do that.
Are there any known issues with this? I will send ktruss output, etc.
upon request.
Running linux uptime gives this ktruss output, looping over and over:
"\0\0\0\0\0\0\0\0\0\0\0\0\0\0\a\0t\^A\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"

but eventually (~45 seconds) later completes with:

I have *NEVER* seen anything like that before. What is going on? ;)
Thanks,
