Metabase 0.50.x high CPU and OOM crashes after upgrading from 0.49

Export

Shows how to fix metabase 0.50.x high CPU and OOM crashes after upgrading from 0.49. Use it when you hit this exact problem. Skip it when your error message or symptom looks different.

TL;DR

Upgrade to Metabase 0.50.7 or newer. The thread leak fix shipped in PR #45253 in the 0.50.7+ releases; the maintainers asked everyone on the thread to upgrade to 0.50.7 and then closed the issue once the fix was out.

Steps

  1. - Downgrading back to 0.49.12 (made the symptoms go away).
  • MB_SQL_PARSING_ENABLED=false (helped some setups but not the OOMs).
  1. The durable fix is the patched release, not a config flag.

When to use

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.
