I have written windows batch script to run apex data loader job every hour. I has run for 2 months without issue.
Today I am deploying the script to new windows 7 and used the lastest Dataloader v34.

Then the script got an issue as below:

At first, I suspect it was a server issue. But finally after google the whole afternoon,  I changed to old version of Dataloader 32. The error is gone.

Just wanna share with you, dont use dataloader 34 for command line job.
