Hi - Similar issues were discussed earlier by others, however I am unable to resolve this from the solutions mentioned in those discussions. [Recommendation for large synonym file](https://discuss.elastic.co/t/recommendation-for-large-synonym-file/42740) I have 2 synonyms/phrases files which are 100MB each currently and may increase in size as we add more data. When I start the ES instance, I get the below exceptions - > [2018-08-20T06:03:47,450][DEBUG][o.e.a.a.i.e.i.TransportIndicesExistsAction] [tAd08LA] timed out while retrying [indices:admin/exists] after failure (timeout [30s]) > org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [SERVICE\_UNAVAILABLE/1/state not recovered / initialized]; I have only one node right now, hence its not failing because of any replication of synonyms files between nodes. Won't ES be able to handle 100 or a 300MB synonyms file? What needs to be done to handle this? ---

same issue here , in my case i have synonyms file with 1 GB and 512 MB , at the time of starting elasticsearch it gives this logs [o.e.m.j.JvmGcMonitorService] [tAd08LA] [gc][369] overhead, spent [1.3s] collecting in the last [2.3s] and finally terminate with OutOfMemory error , ---

How much heap do you have assigned to the node? ---

Have you tried increasing the heap size? I am not sure how much heap such large dictionaries will require, but would not be surprised if processing them will require more than 6GB. ---

I do not know, but would probably try with an even larger heap. ---
