Large number of entries in WTMP file
Hi, I have been exploring a lack of disk space in the /var/log/filesystem. The biggest offender is the WTMP file. When look into the file using utmpdump I can see the login entries. I can see my connection as "root" to the device, but I also see there are entries every 10s even when no one is connected? Is this normal behaviour as it appears to be filling up the log file and taking disk space for not reason. The particular device is a virtual appliance running 12.1.2.
