[MM3-users] mailman-web causing constant 100% cpu load of mysqld

Dear all,

with mailmanweb running, the CPU load of mysqld constantly hovers around 100%

In /var/log/mysql/errors.log I see repeatedly:

2023-01-13 17:22:42 27198 [Warning] Aborted connection 27198 to db: 'mailman_core' user: 'mailman' host: 'localhost' (Got an error reading communication packets) 2023-01-13 17:27:43 29621 [Warning] Aborted connection 29621 to db: 'mailman_core' user: 'mailman' host: 'localhost' (Got an error reading communication packets)

This also seems to affect other services such as dovecot which rely on mysql and at times can't connect to it.

Does anyone have a suggestion what to do about this?

Cheers,

Johannes
