When does this happen?

IF Containers running LiteLLM versions 1.76.1–1.79.1 crash with Out-Of-Memory errors, accompanied by logs of 'Unclosed client session' and 'Error in is_prompt_caching_valid_prompt'.

How others solved it

THEN Disable Slack alerting in LiteLLM configuration as a temporary workaround to reduce memory pressure and prevent OOM crashes. Monitor for versions that fix the underlying aiohttp session leaks, and consider upgrading when available.
