ID: 10908 Title: snmp_uptime: Fix crash for some Fortigate devices Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 Users experienced crashes of uptime checks with some Fortigate devices. This is because the data delivered by these devices does not contain any timestamps. As a solution, the uptime check will not be discovered any more if the delivered data cannot be interpreted as a timestamp. To apply this fix, users have to re-discover the services of the corresponding hosts.
