Hi @muetho68,

Nice catch! This is a known problem related to the parsing of dates, as flexlm does not return years as part of the date, and indeed 2023 had no Feb 29th. I will take a look at it, and try to handle it gracefully. Anyways PRs are more than welcome.

Hi @mjtrangoni ,

as suspected the flexlm_exporter is working today, on a "normal" day. But the next Feb 29th is only 4 years away ;-)
