Emacs frequently hangs

[ldangelo]

I have been chasing an issue with emacs hanging frequently while using lsp. Nothing wakes it up, not C-g nor sending SIGUSR1 signal... I captured the following backtrace using lldb. Any help chasing this down would be appreciated. Do I need to build emacs-mac with debug turned on?

I encounter the same problem as the issue when using lsp-mode. Emacs sometimes crash too. Do you have any new ideas?

[ldangelo]

Not yet... Still digging into this... Interestingly, I disabled lsp and still got a hang on my end. So 'may' not be related too lsp (maybe treesitter?)... Still digging!

[ldangelo]

The plot thickens... I started emacs from the terminal and when emacs hangs it is receiving a SEGV (like the stack trace above shows)... I guess I need to build a debug image and run in the debugger to go further. BTW) This has nothing to do with lsp as I originally thought. It happens when I'm not loading lsp.

[ViktorHaag]

Would it helpful, then, to rename the title of your issue to remove ‘lsp’ from the subject line?

[nvimtor]

Same. It happens most frequently in TRAMP, also. For that reason, I have decided to move to https://github.com/d12frosted/homebrew-emacs-plus which has support for Emacs@30. I do remember a bug related to this was fixed in v30 but can't remember the ticket.

I miss the smooth scrolling but oh well... no more issues with LSP at least, and all feels snappier too somehow.

Got a new M4 Mac before Christmas. Was hoping this issue was related to the intel build. No such luck. Having the same issue. This time I'm editing an org file. I've had to restart 3 times in the last 5 minutes which pretty much renders Emacs useless. Been using Emacs for 30+ years and I'm now looking for alternatives. I doubt I'm the only one having this issue as I took a bone stock doom configuration and was able to reproduce it reliably. I'm happy to help chase this down.

I have the same problem as well. I haven’t been able to solve it yet.
