Hi,
I am having issue with Sync Gateway which had been running for last few months, but suddenly stopped responding. It was giving Gateway timeout (504) error to clients. I was not able to access it from browser or couchbase lite, but sync gateway was running fine on server and I could access base sync gateway url (without db). It started working fine after restarting sync gateway.
When I checked sycn gateway logs, I found a huge number of following logs, which look suspicious to me:
10:19:03.435605 2017-09-18T10:19:03.435Z Changes+: Channel feed processing seq:784 in channel * (to *******)

note: I have replaced my username with ******* in logs.
The same logs had got repeated for all sequences (1-1500).
I think this might be the reason for sync gateway stopped responding to its clients.
Could you please explain the purpose of above logs?
