Priority Experiment: " main error code '-1' for process 'webclient1.tor.1000' "

[pmicos]

I'm running the 'vanilla' and 'priority' experiments and while 'vanilla' executes successfully, 'priority' returns the code '-1' after a while.

By looking the shadow.log file it looks like the error code is referring to the processes 'webclient[1-307].tor.1000':

Any idea what am I doing wrong, and how can I solve it?

Thank you in advance.

You'll want to look at the logs for that tor process, in shadow.data/hosts/.

Looks like I didn't notice that I was running the two experiments at the same time, so different processes were running with the same data. Silly me!

Jan 01 00:15:00.000 [warn] It looks like another Tor process is running with the same data directory. Waiting 5 seconds to see if it goes away.

Thanks anyway for your help!

Yep! You can use Shadow's --data-directory option to make sure multiple simultaneous experiments are using separate directory spaces.
