 Description   

Hi,
We have following setup:
mongos :1
config server :3
mongod (shards):10
all shards are journal enabled.
Every shard have 1.5 tb Disk space.
We make 365 days database.

Get error logs "too many opens files".

After some time of above log we check following:

1> ulimit -n is 35000
2> lsof | wc -l is 7343.
3> lsof | grep mongod | wc -l is 3455.

Why did error "too many opens files" come??

Kindly help me.

Regards,
JRV

We check
ulimit -n
all shards are journal enabled.

Mongod1 become non-responsive. Logs show error "too many opens files".

jitendra, as mentioned in SERVER-6734 it would be great if you could please start a discussion in the mongodb-user groups: https://groups.google.com/forum/?fromgroups#!forum/mongodb-user

Once we've confirmed this is a bug in the SERVER we can open a ticket in the SERVER project here.
