Request Timeout after 30000ms occurred in 6.4 even though it didn't occur in 6.3.2

[wyukawa]

Kibana version:
6.4.0

Elasticsearch version:
6.4.0

Server OS version:
CentOS Linux release 7.4.1708 (Core)

Browser version:
Safari 11.1.2 (13605.3.8)

Browser OS version:
Mac 10.13.6

Original install method (e.g. download page, yum, from source, etc.):
yum

Describe the bug:
Request Timeout error occurred in dashboard.

Steps to reproduce:
1.
2.
3.

Expected behavior:

Screenshots (if relevant):

Errors in browser console (if relevant):

Provide logs and/or server output (if relevant):

Any additional context:
Our dashboard has 2 graph and auto refresh every 10s for last 4 hours data.
Request Timeout error didn't occur when we used kibana 6.3.2 but unfortunately error occurred in 6.4.
Same problem occurred in chrome 68.0.3440.106 but this frequency is less than safari.

can you please provide additional details:

• visualization type
• visualization config (best if you just export the saved object from management->saved objects)
• (both visualizations and dashboard)
• time range you are looking into

does it happen with short time ranges as well ? (like last 15 minutes)

[wyukawa]

Thank you fro relpy!

Our dashboard has 2 visualizations and visualization type is Line

Here is both visualizations and dashboard config

Current our time range is last 4 hours.

If time rage is last 15 minutes, same problem occurs in safari and chrome

@wyukawa Thanks for reporting this. This looks like a known regression which will be fixed in 6.4.1. Here's the PR with the fix: #22558. I'm going to close this issue but if you think that this bug is not the same bug referred to in that PR we can reopen it.
