We are running ElasticSearch 6.7.2 in a 3.2.2 (master/client/data) node setup on kubernetes. I have an ILM policy running to rollover a new index every 7 days, move to a warm stage, and then delete after 1 year. Here is the policy I am using: ```auto { "counter-policy" : { "version" : 615, "modified_date" : "2019-08-23T16:30:08.997Z", "policy" : { "phases" : { "hot" : { "min_age" : "0ms", "actions" : { "rollover" : { "max_size" : "50gb", "max_age" : "7d" } } }, "delete" : { "min_age" : "365d", "actions" : { "delete" : { } } }, "warm" : { "min_age" : "30d", "actions" : { "forcemerge" : { "max_num_segments" : 1 }, "shrink" : { "number_of_shards" : 1 } } } } } } } ``` The rollover worked correctly the first couple of times, but now we are hitting a NullPtrException. I am calling `_ilm/explain?pretty` on my current write index, and am seeing this error (see next comment because character limits): I am able to unstick this by using the retry step API, but it keeps happening again and again. ---

Hi Aaron, Thanks for reporting this, it was definitely a bug. It was previously fixed this for the 7.2.1 and later releases of elasticsearch, see: [https://github.com/elastic/elasticsearch/pull/43353](https://github.com/elastic/elasticsearch/pull/43353) ---

I see. So you didn't backport this fix to any of the 6.\* versions for ElasticSearch that also support ILM? ---

> [@tami](#): > > So you didn't backport this fix to any of the 6.\* versions for Elasticsearch that also support ILM? This was an unintentional miss on my part, thanks for bringing it up. I opened [Prevent NullPointerException in TransportRolloverAction (#43353) by dakrone · Pull Request #45935 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/pull/45935) so it will be in the next 6.8.x release. ---

OK great thanks. We are currently using 6.7, will it get backported to there too? Or will we need to upgrade to 6.8 ---

> [@tami](#): > > We are currently using 6.7, will it get backported to there too? Or will we need to upgrade to 6.8 There aren't any more 6.7 releases planned (except in the case of security vulnerability fixes), so you'll need to upgrade to the latest 6.8 release once the next version is out. ---

Hi, Is there any ETA on when a new 6.8.\* version will be released containing this fix? Thanks. ---
