hello..recentlly I got a weird elasticsearch crash problem and it lasts nearly one month .since I reindex some of my index to enlarge the shards from 1 to 6..and the error like following
```auto
[o.e.b.ElasticsearchUncaughtExceptionHandler] [es-cn-9lb3e7861000eg3q5-7819d1df-0001] fatal error in thread [elasticsearch[es-cn-9lb3e7861000eg3q5-7819d1df-0001][clusterApplierService#updateTask][T#1]], exiting
java.lang.StackOverflowError: null

```
then I search the source code with elasticsearch 7.10.0 ..find the Parameter.getDefaultValue canbe infinite loop when it is the ` Parameter` ..but don't in which case it can be triggered.
this crash periodlly happens ,in 4:00 10:00 16:00 22:00 ..and every master node crashs one by one ..then the cluster back to normal ..
any idea about this looking forword your replies thanks~

I'd upgrade to 7.17 at least. And better is to switch to Elasticsearch 8.14.2.

Thanks a lot for replying！！finally I get the exception stack from the `/_nodes/hot_threads` found a period index updating cause the merge error, but don't know why crash every 6 hours instead of crash immediately 🥲 ， whatever currently we can avoide this error ， and may upgrade the version in further
