Duplicate entries in wtmp

[Jeffrey M. Nolle]

I have been experiencing duplicated entries in my 'last' command output. I cleared out the wtmp file last week, but the problem persists. This is happening several times a day, but I do not see any specific patterns (system load, tty, user, time, etc.). This is an N-class system running HP-UX 11i (B.11.11).

(all ip addresses the same)

There are many thread about wtmp and utmp

I had already done a lot of research prior to posting my question. I found a lot of information on how to repair a corrupt file, but nothing on how to prevent the corruption (if you consider this to be corruption) from occurring in the first place.

I'm still open for suggestions.

Thanks.
