type-at-point stops working after a while…?

[Viktor Hedefalk]

Hi,

I'll move this to a new thread. I guess I'm not doing something I'm supposed to do or doing something I'm not, but I can't seem to track it down from looking at the Emacs plugin.

This is a section of my server log.

So type-at-point was working nicely, and then I leave the computer be for 3 hours. After that type-at-point gives bad answers and then I just close the socket from the client and run "init-project" again and then it works once more. Is there some kind of refresh I should make that I'm missing?

Any idea why stuff seem to "degenerate" over time?

Thanks,
Viktor

Hey Viktor,

Raised https://github.com/ensime/ensime-server/issues/925 - as mentioned in the ticket - my guess is that emacs is dropping the idle connection. 

I suspect either a change in the config or a heartbeat should be added.

Thanks for reporting (feel free to investigate further/PR ;) )
Cheers

Rory
