Crash on large input SIGSEGV: segmentation violation --13B model

[watcher60]

I'm running ubuntu 22.0.4 with 32 GB of RAM, with Auto-gpt pointed at LocalAI using model Manticore-13B.ggmlv3.q5_0.bin, I believe I'm up to date on LocalAI and associated libraries.

I have been stable previously but using this model it appears when the input is getting to a certain size I am getting a SIGSEGV: segmentation violation. Can anyone give any pointers on any adjustments I could make, or areas to look into as I'm not familiar with the error.

Error:

Just to advise I switched models to use Wizard-Vicuna-30B-Uncensored.ggmlv3.q5_0.bin and the repeated crashes went away. Closing as presume a local issue (and I should have tried the apply model option to see if that resolved the issue)
