Thanks to the *huge* number of different LibraryFileAlias objects this script
|
|
9 |
will fetch when parsing multiple log files from scratch and the fact that we
|
|
10 |
overwrite storm's cache with something that caches *everything*, this script
|
|
11 |
may end up eating all your RAM. That shouldn't happen in general as we run
|
|
12 |
it multiple times a day, but if we ever fail to run it for more than a week,
|
|
13 |
we may need to add a hack (store._cache.clear()) to clear the cache after
|
|
14 |
updating the counts of every LFA, in order to get through the backlog.
