Hello,
An of course cron-tasks are failing for other reasons to, so contact me (jira-bug preferred) if you have a problem.
What's about https://jira.toolserver.org/browse/TS-1421 ? I opened this bug months ago and there is still no solution. I still get a lot of stupid mails every day and a lot of cron jobs does not get started (randomly).
frustrated greetings, Aka (André)
