[mrtg] Forking problem: invalid log file format

[Christopher Poetzel]

hello all,

i am having issues with mrtg 2.9.2 forking feature.  I run it on Redhat 
6.2 and i assume that linux can do forking.  I am testing forking on just 
one router and get these errors for about half of the interfaces:

Rateup ERROR: /usr/local/mrtg-2.9.2/bin/rateup found 
130.202.129.13_vlan666's log file was corrupt
          or not in sorted order:

When lookin at these two log files, the appear like so
# more 130.202.129.13_vlan666.log
971710737 xxx at 130.202.129.13 Descr   Loopback129     3  
xxx at 130.202.129.13 Descr   Null0   2 971710737 0 0 0 0
971710200 0 0 0 0
971709900 0 0 0 0
971709600 0 0 0 0

The log file is oviusly messedup somehow.  this only happens when i try 
to use the Forks: 4 option.  anyone had any similar problems.
any help would be appreciated
