@zhaomenghuan, thank you again! What OS are you using? I would like to reproduce the issue with and without your changes; do I have to hibernate my OS and that's all I have to do?

[zhaomenghuan]

@kittaakos I am using macOS. I can't reproduce the problem with the theia examples and Arduino Pro IDE. Currently, it can only be reproduced in the application I built.

👍 Thanks for the info. Me too, at least this simplifies the verification.

Good to know.

I was not aware of it, but macOS can be configured to go to hibernation mode instead of sleep with pmset. Did you tune pmset on your side?

[zhaomenghuan]

In my impression, I haven't made any settings about pmset, and used the default behavior of the system. If SIGPIPE is not processed in my application, the process will die in sleep mode. I have analyzed the memory-related data and can confirm that it is normal.

[kittaakos]

OK, fair enough. Your contribution is super useful for Electron clients; I will figure out how to reproduce it locally and try to merge the PR this week so it will be part of the next release.

I have verified it with the demo version of SmartSleep on macOS: QuickSleep > Hibernate Now. It works great 👍
