ProjeQtOr 8.5.4: Cron and Grouped Mails

Is it normal that I manually have to restart the Cron service on the administration page after I changed the "Sending of grouped mails" setting in the global Mailing preferences?

I wondered by no mails were sent any more at all after enabling grouped mail sending... Until I noticed that on this completely different Admin screen the information about cron said that grouped mails would still be disabled. Stopping/Starting cron there solved the issue.

Hello,


it's normal to have to restart the cron after changing a parameter used by the one if to take it into account.
The cron works with the information we defined before launching.

Ok, good to know.

Just out of curiosity, how is ProjeQtOr's cron technically implemented?

PHP scripts running in the web server normally have a short time limit.

For most php applications that need to perform regular tasks, a separate cron-job executing a helper script of this application has to be configured, but that was not necessary for ProjeQtOr, as far as I can remember...
