We had a bit of an issue with stability when it came to running some large files. We kept getting an error. In the end, we had to divide the files and process it via multiple files because of the way we implemented them. Large file processing also seems to take up more memory.

We had issues in Munit but rarely any stability issues.

We have not had stability issues.

This is a stable solution.

The version that I am using, 3.8, is quite stable. My understanding of version 4 is that it is not stable, yet, because it is new, and it will take some time.

No problems with stability have been brought to my attention, although once the system is in production, a different team handles it.

The stability of this product can be improved.

CloudHub stability has been an issue. However, this is being worked on.
