Strange behaviour on AIX 4.3.3

Hi ! 

and Happy New Year to everybody !

This afternoon we've seen an abnormal size for the msg.txt file in client 
directory. Here is output :

PSP100 /opt/hobbit/client/tmp>ll
total 934872
-rw-r--r--   1 root     hobbit         0 Jan 11 10:43

PSP100 /opt/hobbit/client/tmp>> msg.PSP100.txt.86546

As you can see a file reached 500M in size !! You could notice that some 
files were created by 'root'. Well... it's not good 'cause that meaned 
someone in my team launched Hobbit with this account ! Anyway, it's not 
the first time I see such size for this file on the machine. 
How may I prevent that ?

Sincerly,

Thomas
