[MM3-users] Loads of postgres requests: SELECT "django_q_ormq"."id", "django_q_ormq"."key", "django_q_ormq"."payload", "django_q_ormq"."lock" ...

Hello,

I run a small mailman3 server (6 lists, less than 100 users), and I can't access anymore to the administration web page for one of these lists:

Something went wrong Mailman REST API not available. Please start Mailman core.

The other lists seems OK.

Looking at the postregsql logs I see a full load of these requests (4 to 5 per second!): LOG: statement: SELECT "django_q_ormq"."id", "django_q_ormq"."key", "django_q_ormq"."payload", "django_q_ormq"."lock" FROM "django_q_ormq" WHERE ("django_q_ormq"."key" = 'default' AND "django_q_ormq"."lock" < '2020-04-09T07:57:37.828200+00:00'::timestamptz) LIMIT 1

Any clue appreciated. Many thanks in advance,

_g.
