Yes, that is the problem. Someone else had this problem [last week](https://discuss.elastic.co/t/logstash-filter-date-match-not-replacing-timestamp/306364/22) and solved it by using mutate+gsub to change the abbreviated month name to a month number. The problem is that that particular locale requires a period at the end of the month abbreviation. So `May 2 10:40:49` works, and `Nov. 2 10:40:49` works, but `Nov 2 10:40:49` cannot be parsed.
