samba - Apr 2005 - Samba related errors

Can anyone help me figuring out the following errors? 

I am using Version 2.0.7 on Solaris 2.6 


inetd [155]: /opt/samba/bin/nmbd: Hangup
inetd [155]: netbios-ns/upd server failing (looping), service terminated


 I have few customers unable to convert images to JPEG format.

 I don't know if the above errors is the cause of the condition

Thanks in advance
