I recently upgraded our license servers from to Since then our logs only contain timestamp lines:

4:34:05 (lmgrd) TIMESTAMP 1/3/2018
10:34:05 (lmgrd) TIMESTAMP 1/3/2018
16:34:05 (lmgrd) TIMESTAMP 1/3/2018

No license usage is logged. This makes our license usage statistic tool fail horribly and makes debugging impossible.

I start the server with the options

# /usr/sbin/lmgrd -l +/var/log/flexnet/flexnet.log -local -c /etc/flexnet

This has been working for years but now suddenly stopped generating useful information.

Is this a known behaviour? Or even worse - is this a desired behaviour?
