NAV 5.9.1 Suddenly, since yesterday, a lot (but not all) of the navtopology cron jobs sends an email with "navtopology is already running" An example: /var/log/cron Apr 30 09:35:00 <hostname> /usr/sbin/cron[69867]: (navcron) CMD (navtopology --l2 --vlan) 10 minutes later an email arrives Date: Tue, 30 Apr 2024 09:43:35 +0200 (CEST) Subject: Cron <navcron@bjarne> navtopology --l2 --vlan navtopology is already running (69867) What can trigger this error? var/log/navtopology shows that the job runs as usual. (Last lines in the run is "deleting unused prefixes/vlans") The one thing that changed before this error turned up is that the server running NAV was moved behind Cisco ACI and a (application centric) firewall. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo@uit.no Dep. of Information Technology --- Univ. of Tromsø
