mongo3.0 restore fails with error Failed: restore error: insertion error: EOF

Question

I'm trying to restore a database with 100 collections (800GB) using mongorestore which was taken as a backup from mongo 2.4.4. I used the following command:

mongorestore -u <username> -p <password> -d bp_prod079 
             /data/backup/2015-11-28/bp_prod079 --batchSize=100

I'm using batchSize =1000, 500, 100 to try to make it work. I'm getting an insertion error after 10-15 collections. It almost runs for almost an hour and half perfectly when I get this error.

Failed: restore error: bp_prod079.ANEpisodeBreakdown: error restoring from /data/backup/2015-11-28/bp_prod079/ANEpisodeBreakdown.bson: insertion error: EOF

Answer 1

For me with a minor batchSize works. First I had --batchSize=50 and changed it to 10 --batchSize=10 and perfect.
