The INFO "Starting job x" and "Job x done" logs are only logged for the
automatic executing of the cron by the cron worker. When running the
cron manually via its form view, no INFO was logged.
The technical support is reporting problems where a cron server action
is running twice at a same moment leading to problems such as
mass-mailing sending emails twice. There is a mutual exclusion mechanism
for cron workers but no exclusion mechanism seems in place for http
worker vs cron worker. Logging the "run manually" actions will help us
figuring out the problems.
