Lustre File Locking

[crutching]

Getting following error message trying to lock file before a citation is displayed. We are working on a lustre fs, which i assume is the problem.

Traceback (most recent call last):
  File "~/lustre1/galaxydev/galaxy/lib/galaxy/managers/citations.py", line 149, in to_bibtex

Are you sure you are mounting the file system with the flock option? Should be needed to enable file locks on lustre.
