Hi Yoon,

Thanks for explanation..

Here is situation....

When I submitting a Java job to 1 VM and to 1 host in that pool.

What will happen to the job if both machines were suspended due to some keyboard activity (SUSPEND = $(KEYBOARDBUSY))

i) whether the condor will wait till the machine to resume to do the job..

ii) otherwise it select appropriate another machine to complete that job..

Tell brief in VM prespective....

Thanks
