Hi @melema

Thank you for reporting. It looks like CouchDb is the root cause of your replication error.  
Could you please provide some details about:

1. How many docs does your whole server have
2. Server load at the time of the failure
3. If this is happening consistently with _some_ users and working fine for others.
4. How you are running CHT-Core: for example are you using docker?
5. Which version of CHT-Core and CouchDb you are using.

Thank you!

1. 5252733 docs on medic database
2. cpu usage was less than 50% and memory usage was low
3. This is happening consistently with some users and working fine for most users.
4. We are using docker
5. CHT-Core 3.13

Can you please also share storage drive usage?  
I’m going to ask our Site Reliability Engineers about this.

Disk usage is at 40%. There is more than enough space.

Hm, we haven’t seen this issue before. After some quick searching, lets verify your disk iops. Can you find out that information and monitor that metric during load?

The logs also mention specific docs, `ba1e817b-4d1f-4708-a41e-8753c86f757b` and `6197b8f4-2650-45e6-ab3e-b7e755e59560`. Can you try accessing those docs with curl or with fauxton and see if you get any errors?

Yes @diana , we get the same for both documents uuids…  
{  
“error”: “not\_found”,  
“reason”: “missing”  
}

For existing document uuids (that we pick from the instance as a sample), we get the document as a response.

Looking at the couchdb logs, it seems that a put is crashing the shard?

```auto
[notice] 2022-07-04T10:13:23.994029Z couchdb@127.0.0.1 <0.22169.2508> b56fc793d3 echis-production-go-ke.lg-apps.com 44.199.169.171 medic-replication PUT /medic/6197b8f4-2650-45e6-ab3e-b7e755e59560?new_edits=false 500 ok 5

```

So `medic-replication` tries to write `6197b8f4-2650-45e6-ab3e-b7e755e59560` to the database.  
And then, immediately the shard crashes.  
What is `medic-replication`? Is it the user you were trying to log in with? Or is it some other user that pushes data into your DB?
