See the following Force Quit popup message:
Your system has run out of application memory.
Firefox uses 57GB memory, the other apps use only 1% of that. I've seen this many times (>10) by now, and it's always around 55-57GB. The internal SSD has 25GB available, the system has 8GB RAM. I don't know how it can use 57GB because that is not available.
This message results in macOS killing several apps automatically. Strangely Firefox is not killed. I have to do that myself. Yesterday this happened, two days ago, but most of the time it's not that often.
Below you see the current memory usage, with Firefox using almost 9GB, and the webcontent/extensions using another 6GB, so 15GB together. I started FF about two hours ago.
Today I disabled a lot of addons, but I don't see any improvement.
Questions
- What is going on here?
- How can I see what is causing this problem?
- How can a system claim this much memory while it is not available?
