    3131Here are some things that FOAM admins should be aware of and watch out for.

     33=== Administrative list-resources blocks other FOAM operations ===
     34
     35In FOAM 0.6, an administrative list-resources call lockes the FOAM database, and thus blocks other FOAM operations. If an experimenter tries to use FOAM while this is happening, they'll get a "database is locked" error; if they retry, it should work. (If the error persists, something else is probably wrong.)
     36
     37The FOAM monitoring code (from the 'tango-monitor-foam' package) does an administrative list-slivers whenever it runs, and it runs once per minute by default, so there's small window each minute (a second or two) when this can happen.
     38
     39This issue is being tracked in [https://openflow.stanford.edu/bugs/browse/FOAM-227 JIRA ticket FOAM-227], and should be fixed in FOAM 0.8.
