Fatal error on [IO wait] #561

Open stvno opened 5 years ago

stvno commented 5 years ago

While running the official tegola docker 0.8.1 with the data in postgis and an S3 cache (digital oceans spaces) I get seemingly random fatal failures when seeding my cache. I'm using a tilelist to seed about 400k tiles and this is the second time Tegola crashed with an [IO wait] message. This time I did get the entire stacktace, see below. If I rerun the seed it wil continue beyond the last tile before the crash, as such I do not think it is a data issue

Okay the crash seems to be happening in the runtime allocator when trying to make allocate enough memory for the new ring here:

https://github.com/go-spatial/tegola/blob/master/maths/makevalid/plyg/builder.go#L38 


ring.Points = make([]maths.Pt, 0, len(b.parts[0])+len(b.parts[1]))

I'm not sure what we can do about this, not even sure if we can catch this type of panic. It's getting thrown here: https://github.com/golang/go/blob/master/src/runtime/malloc.go#L784

I'm looking to see if there are any google entries on it. I could force a GC run right before it?

gdey commented 5 years ago

Just relevent information for this:

Go version used to compile: 1.11.2 Travis build link: https://travis-ci.org/go-spatial/tegola/jobs/453088789

ARolek commented 5 years ago

@gdey yeah this is the same issue we researched before. Catching out of memory errors is not currently possible. I don't know if forcing a GC run is right either (though we're doing that in the seeding code). I think as we have more time to optimize the memory usage of the processing algo this should naturally be addressed.
