    3333=== Administrative list-resources blocks other FOAM operations ===
    3434
    35 In 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.)

    3737The 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.
