RangeError: Maximum call stack size exceeded

Hi @iamnewspecies.

This is not a known issue. Have you confirmed that this error is due to cls-bluebird? It seems more likely to me that it's not, or that you/Sequelize are using cls-bluebird incorrectly and not exiting contexts after each request. I guess that could result in every request being stacked on top of the last.

Please come back to me when you've investigated further.

I just had this same error in production on several servers....

My apologies. This does sound like it could be an bug in cls-bluebird.

@DavidMorton Can you please share some more details?

• Are you using promise cancellation?
• What version of Node are you running?
• Latest version of cls-bluebird?
• What version of bluebird are you using?
• Any other code you can share

I'll try to get to the bottom of this if I possibly can.

We're getting this suddenly in production as well. Ex:

Unhandled rejection RangeError: Maximum call stack size exceeded
    at executorPatched (/app/node_modules/cls-bluebird/lib/shimOnCancel.js:1:1)

    at executorPatched (/app/node_modules/cls-bluebird/lib/shimOnCancel.js:37:21)
    ...

• Node v10.15.2
• Sequelize v5.21.3
• bluebird v3.5.5
• cls-bluebird v2.1.0

We're not using bluebird/cls-bluebird directly at all, but it's a dependency of Sequelize so somewhere under the hood they're using. We're trying to find a way to replicate outside of "let it run in production for about 2 hours...", once I can get more info I'll post here, it may help others.
