Activity Log + Supertable + something = site crash.

[wihodges]

Ok so I had a really strange issue, where all of the sudden any entry with a supertable field could not be resaved. Doing so caused the entire backend to crash. The error I was getting:
'PHP Fatal Error' says: Allowed memory size of 268435456 bytes exhausted (tried to allocate 528384 bytes) in /home/repopath/craftcms/cms/src/elements/db/ElementQuery.php on line 2073. I don't think it was a memory problem as memory available was larger than allocated and I also spent a good amount of time changing php.ini settings. With Xdebug enabled I would get maximum nesting level to any number I set. Nothing seemed to fix the issue and the logs weren't telling any exceptions.

After hours of trying to debug finally started disabling plugins. Appears in this instance Activity log did not want to play nice. I can't quite seem to figure out how or why this is happening because I have another site with both plugins installed and both updated to Craft 3.2.9 and saving entries with supertable field still works. I do notice that the backend is noticeably faster now with it disabled.

Hopefully this is just a random bug but unfortunately I just need to disable the plugin.

Hi @wihodges Thanks for reporting this issue. Is it possible that you could give me some more info:

• What fields did Supertable have?
• How many rows did Supertable have?

Or if possible send me that db to test it with?

Many thanks

I have a similar issue, and its reproducible when saving or reverting to a previous entry version. This entry did contain some Super Table fields. I'll try to investigate
