[MM3-users] "mailman start" hangs

Hi,

When starting mailman in a terminal, then it works:

--8<---------------cut here---------------start------------->8--- $ mailman start Starting Mailman's master runner $ --8<---------------cut here---------------end--------------->8---

But from "cron", it seems to hang. Output of pstree:

--8<---------------cut here---------------start------------->8--- |-cron(3022)---cron(21962)-+-mailman(21986) | `-sendmail(22043)---postdrop(22044) --8<---------------cut here---------------end--------------->8---

So it seems, that mailman does not go into the background, and the email with the output is never sent...

How could I solve this issue please?

TIA for any hints,

       Peter
