Hello!
MongoDB 3.5 on docker container.
I’ve been experiencing an issue related to mongodump. I tried to create a dump from docker container this way :
docker exec $i mongodump --archive --gzip > $backupmongo/dump_mongo.gz but it constantly fails while dumping specific collection :
Failed: archive writer: error writing data for collection COLLECTION_NAME
to disk: error reading collection: Unknown element kind (0x65) / Mux ending but selectCases still open 4
I suspected that it may be related to OOM but I couldn’t find anything which indicates a such reason.
Has anyone encountered such a problem?
