starting Bro as different user

Hi
I had installed Bro as root.
I have no trouble starting Bro logged in as root.
When I try to start Bro, logged in as another user id, I get the error below.

[BroCluster] > start
error: cannot aquire lock: [Errno 13] Permission denied: '/opt/bro/work//spool/lock.9215'

Any suggestions to fix this?
Thanks,Sirisha.

It looks like you ran the cluster shell as root. Just delete the 'lock.9215' file as root and make sure the /opt/bro tree is owned by the user that you'd like to run bro as.
