Error reporting on MGM is not active

Dear EOS community,

Following the citrine upgrade of our production instance, we noticed that the /var/log/eos/mgm/error.log file is not filled in any more with errors coming from the FSTs, it stays always empty.
How is it possible to troubleshoot this ? We can’t see any related issue in the several log files…

Thanks in advance.

This has been kindly fixed in version 4.2.23 of MGM.
