utmp and wtmp are user accounting information, used by commands like "last" and "who". Is the PI collector logging into the box repeatedly?

Re: /opt partition keeps filling up >> Are you really sure it's not the /var system that's full? Check /var/logs. Eliminate any large log files there.

We use OSI PI for data archiving, but one collection group associated with a heavily loaded CP is always going offline. This results in monstrous log files, especially /var/adm/utmp* and wtmp*. Until I can shed some load on the CP, the only thing I've found to do is /dev/null those files, and restart PI. This has worked well enough in the past, but lately the /var partition is FULL and even rebooting the 51B after clearing out these log files doesn't help.
