Database replication stops working after 10 minutes (replicator crash)

[martinschoenwandt]

I am currently working on a proof of concept prototype application that basicaly performs the below in order to prove how stable CouchDB replication is.

But unfortunately by looping the test below in around 10 minutes replication suddenly stops wokring from counta->countb and seems like the only
thing that is working afterwards is deleting replication document and both databases and start all over creating databases etc.

Description

I have been able to reproduce this several time (test application written in C# and using my own small CouchDB implementation using RestSharp).

I have attached log file that shows that the replication process crashes - so is this a bug and what to do from here??

Steps to Reproduce

Precondiction:
One 'counta' database with one document: {
"_id": "countId",
"Value": 0
}
One 'countb' database with one document: {
"_id": "countId",
"Value": 0
}

Test application (Merge the highest number wins):

• Remove A->B replication if exist (database counta->countb)
• Remove B->A replication if exist (database countb->counta)
• Create A->B replication (database counta->countb)
• Wait 5 seconds
• Set count A = 0
• Wait 5 seconds
• Read count A = 0
• Read count B = 0
• Remove A->B replication (database counta->countb)
• Set count A = 1
• Set count B = 2
• Wait 5 seconds
• Read count A = 1
• Read count B = 2
• Create B->A replication (database countb->counta) (Creates an expected conflict)
• Wait 5 seconds
• Read/Merge count A = 2 (Conflict merged 2 revisions - Value = 2 wins)
• Read/Merge count B = 2 (Conflict just handled and merged by Read A so nothing to do here)
• Wait 5 seconds
• Read count A = 2
• Read count B = 2
• Done - Loop

Expected Behaviour

It should continue working...

You need to upgrade to CouchDB 2.3.1.
