node: ../deps/uv/src/unix/async.c:136: uv__async_io: Assertion `n == sizeof(val)' failed. #12853
Description
- Version: v7.10.0
- Platform: Ubuntu 16.04.2 LTS
- Subsystem: libuv
node: ../deps/uv/src/unix/async.c:136: uv__async_io: Assertion `n == sizeof(val)' failed.
I note that this is supposedly a solved issue at libuv/libuv#1171 but I am still seeing it in v7.10. I am running an smtp proxy server which is listening on around 35 interfaces / ports and I am seeing this as an intermittent crash. The code is written in Coffeescript and is being run by coffee version 1.12.5.
I'm happy to help with further debugging if needed but I'll need clear pointers as what to do. However this is badly affecting a live system. Crashes have gone from around one a day to now every 10 minutes or so. Any pointers as to how to avoid the problem in the short term would be appreciated.

I think this might just require a libuv update in Node itself? /cc @saghul @bnoordhuis

@addaleax Yep, once the next stable is out we'll do the update! No ETA as of now.

I'm having this error pop up on an API I am developing. I'm part of a very small team and I really can't afford to have this blow up when I show it to a client. Did anyone figure out how to put a bandaid on this issue? Does rolling back the version of Node fix the problem? If so, what version?
