Warmup function times out frequently

See original GitHub issue

My warmup function errors about 2 times a day with error Task timed out after 120.08 seconds. The output in the logs would be

START RequestId: 123456789 Version: $LATEST
END RequestId: 123456789
REPORT RequestId: 123456789	Duration: 120083.94 ms	Billed Duration: 120000 ms Memory Size: 128 MB Max Memory Used: 61 MB	
2019-01-30T15:38:08.511Z 123456789 Task timed out after 120.08 seconds

So it doesn’t even log

2019-01-30T15:31:08.716Z	987654321	Warm Up Start

as it does on successful invocations. Any idea why this is?

The warmup function is not in a VPC (the functions it calls are, though) and frequency is 5 minutes.

That’s why I think that the ticket should be submitted to AWS. Because it seems to be an intermittent issue that happens for no apparent cause.

We have been facing the same issue. Raised a ticket with AWS with no avail. However, these timeout issues are not limited to just warming up lambdas. I have seen intermittent timeouts on normal execution lambdas too. And this started happening around feb. We had existing code in prod, and with no changes it started timing out. Of late even warm-up lambdas timeout after 10 seconds, and this happens for about 8-10 minutes, and then resumes normal function. Still waiting on AWS to respond to it…

@idhard Nope, they say they are still investigating. It seems to be a recurring problem.
