| Subject: | CPU spin when run under batch (or Sun SGE) |
I am on a quad Opteron from Compaq running Linux,
Linux mash.networkmcs.com 2.4.21-15.0.2.ELhugemem #1 SMP Wed Jun 16 22:36:51 EDT 2004 i686 athlon i386 GNU/Linux
I have a simple process that I control by using your SSH to a Win2K box running WinSSHD. Usually works great (thanks)!
But, when I attempt to run it via batch or Sun SGE, the time spent in my code waiting for the ssh->cmd('command') to complete spins the local CPU 100%.
"close (STDIN)" fixes this.
An enhancement to the open/login process would be a retry count. I had to code this because my Windows box gets too busy and refuses connections occasionally.
Again, thanks for this code. It has saved me a huge amount of pain since I was able to replace a Windows based spooling system with it.
