[Feature] Auto restart on encountered errors

[Fronix]

I'd like for meilisearch to be configurable with a list of errors that if encountered, it will automatically restart the instance. Reason behind this is there are certain issues with windows, example is this error
The paging file is too small for this operation to complete. (os error 1455)

It will pop up sometimes, it's not consistent, and I cannot change the paging file settings. Sure it would be better to fix the actual errors but there as been very little headway in these types of issues and having a script pinging meilisearch just to potentially restart it seems inefficient.

Hi @Fronix , while auto-restarting on paging file errors could keep things running, it sounds like it would be masking an underlying issue. Could you help me understand your issue a bit better?

• What's the size of your dataset (number of documents and average document size)?
• Are these errors happening during indexing, searching, or both?

This information would help us identify if we can solve this through Meilisearch configuration rather than working around the errors.

Size is around 4-5GB so nothing huge

I really can't say when the errors happen, sometimes the logs indicate it has been indexing, sometimes it just looks like normal searches have been made. Right now I don't have any logs to share. This error is so random i cannot enable more verbose logging since it could take days or weeks before it happens again.

I've had monitoring on both CPU and RAM and the paging files are system handled (we are not allowed to change these).

Thanks for the details! Given that the error occurs unpredictably and isn't directly tied to a specific indexing or search operation, handling automatic restarts might be best configured at the infrastructure level.

Since this request falls outside the scope of the search engine itself, I’ll go ahead and close this discussion. However, I encourage you to open an issue on the Meilisearch repo. That way, the engineering team can investigate these errors or provide recommendations on configuration optimizations.
