Snowflake server keeps failing unexpectedly

The snowflake server has failed twice now in the last two weeks.

After the first failure, we upgraded the capacity of the Snowflake bridge (#40085 (closed)).

Today when it failed we received an alert from monit: https://lists.torproject.org/pipermail/anti-censorship-alerts/2021-December/000786.html

Unfortunately, in my rush to fix it I didn't check the CPU usage :/ let's use this ticket to track the issue and note what we notice the next time it occurs.
