0.62.2 broken (crashes on startup)

[micw]

Hello,

I got this issue when I switched from 0.61.2 to 0.62.2: RocketChat/Rocket.Chat#10114 (comment)

The cause is a segmentation fault with node js 8.10: nodejs/node#19274

The breaking change is between 0.62.0 and 0.62.1 docker image:

docker run --rm -it library/rocket.chat:0.62.0 node --version
v8.9.4

docker run --rm -it library/rocket.chat:0.62.1 node --version
v8.10.0

Proposed fix: use node version 8.9 as base image.

as stated at RocketChat/Rocket.Chat#10114 (comment) I was able to run 0.62.2 .. do you have any additional details?

I have created a copy of my environment and upgraded from 0.61.2 to 0.62.0 - the server started with no problems.

Then I upgraded to 0.62.1 - and it dies at the same point as before:

I downgraded again, enabled debug logging in admin view and upgraded to 0.62.2. Similar result:

I ran the container with a sleep command, attached a shell and executed "node main.js" in the shell. Same result as above plus one more log line:

Segmentation fault

[sampaiodiego]

@micw this is weird.. please try removing your current image and pulling it again (docker rmi rocket.chat:0.62.2 and docker pull rocket.chat:0.62.2).

if after that you end up with same issue, please try using our own image: rocketchat/rocket.chat:0.62.2

[micw]

Same with freshly pulled image. With rocketchat/rocket.chat:0.62.2 it works - but that one uses node 8.9.3

Since it worked I've created a pull request to force image to use 8.9.. let's see how it goes

[sampaiodiego]

looking at @micw logs again I noticed ReplicaSet OpLog: Disabled , so I tried again using this same configuration and it crashed to me as well.

I'll leave this closed and add this new info into RocketChat/Rocket.Chat#10114 so we can keep talking there, as it not seems to be a docker image issue

[micw]

@sampaiodiego Seems to be the combination of "OpLog: Disabled" and node 8.10. So the docker workaround might be a good thing until the root cause is fixed.
