error message: Sending key 'preset' to UI failed, out of space

Postby alex stone » Wed May 15, 2019 1:33 pm

Tim, as the error message says:

Sending key 'preset' to UI failed, out of space.

It's repeating and scrolling up the terminal steadily.

Is this to do with the number of tracks i currently have, or the number of lv2 instances currently running? (35)

Alex.


EDIT: The error hasn't shown up on restart. A session glitch when manipulating LV2 presets?

I'm going to give you a new handle: The Punisher. :wink:
Delivering punishing tests, ha ha.

Wow, that error isn't found in our source, it seems like a system error telling you out of memory or something.
It might very well be the LV2 synths (or our encapsulation of them) eating up memory, as logically they are the most resource intensive.

Keep an eye out and try to capture any messages and keep an eye on memory usage. I wish I could see it.
Maybe we should have a memory meter besides the CPU meter.

Tim, i have 64GB of ram, and it's nearer 20GB with the current setup. Not sure it's memory, but you're the dev, not me. But you've given me a clue to look beyond Muse, and i shall do that. I'll keep an eye on the data, and if i can capture anything useful i will share.

Regards,

The Punisher.

Quick postulate: "Out of space" might not mean the same as "Out of memory".
There might only be a certain amount of 'space' reserved for the operation (by whatever is printing that message),
or say, maximum number of such operations or synths etc.

Yep, i'm wondering the same. It might be i can only add a certain number at a time, then i need to save,close, open, and continue.

It seems ok now.
