Rack crashing in a seemingly random way when using Prism

[spectromas]

I'm not what information to provide here because I don't know how to reproduce it but when using Prism on linux, Rack is crashing at apparently random points. I think the crashes are not related to any particular steps, as far as I can tell, but after a while (whether adjusting Prism or adjusting something else entirely in the patch) Rack crashes.

The log says the following:

I am using Rack with Jack running at 44.1khz, 1024, 3. Seems like there is an issue with the cpu mode running at 48k when the Rack sample rate is not 48k?

Hi,

Is it misbehaving in 96Khz mode?

Annoyingly, I can't reproduce this now so I suppose this should be closed. I think I did try 96Khz mode and the stability improved but I can't say for sure now.
