We've seen that on Macs before, but only in fairly resource limited
virtual machines. What are you running on exactly?

Ashesh recently added a parameter to allow control of the timeout on
the database to avoid this issue - you could try increasing that. Try
adding something like this to config_local.py:

# SQLITE_TIMEOUT will define how long to wait before throwing the error -
# OperationError due to database lock. On slower system, you may need to change
# this to some higher value.
# (Default: 500 milliseconds)
SQLITE_TIMEOUT = 1000
