Fatal error: runtime: out of memory sync gateway


#1

Hi,

I got the"fatal error: runtime: out of memory sync gateway " every time I running the batch job via sync gateway to get a huge amount of json to check and update, any idea how to resolve?

My program is a web application which need to do a batch job to check all the cases to update, currently it will via sync gateway to get the json to check and update (total request may be around 100k - 200k)

Below is my config.

Couchbase Server 5.5
Sync Gateway 2.0
Sync Gateway RAM: 16GB

Error details:

fatal error: runtime: out of memory
