AIX client causes hobbitd_rrd on server to core dump

[Matt]

Greetings - I'm trying to monitor some AIX boxes, but they are causing the hobbitd_rrd to core dump on my hobbit server. 

Server is CentOS 5.2 running hobbit/xymon  4.2.2 (server)
Client (aix01) is an aix 5.2 box running hobbit/xymon 4.2.2 (client). I have also tried using the precompiled AIX client from docum.org. Any suggestions would be greatly appreciated!
