log.sipd file is always empty with loglevel Debug

Hi,

Build Date=03/13/20

I have currently s strange issue with the log.sipd file. It is always empty even when I enable debug mode:

ant1-sbc06a-access# log-level sipd debug

completed

ant1-sbc06a-access# log-level sipd notice

completed

ant1-sbc06a-access#

ant1-sbc06a-access# sh logfile

...

0     Dec 9 09:31:19 log.sipd

...

on system-config, we have:

 system-log-level            WARNING

    process-log-level            NOTICE

ant1-sbc06a-access# sh loglevel sipd

Log Levels for process sipd:

    loglevel=NOTICE
