CUPS 1.2.2 - cups-polld exited on Solaris client

[angelb]

Hello all;

Here, I have configured a Solaris 10 client with CUPS 1.2.2. Before
starting cupsd, I decided to run truss against it. Not long after
cupsd started, the cups-polld daemon received a SIGTERM.

See the following truss output:

Does the truss report provide any clue as to what's causing the child
processes to get terminated?

While my AIX client was started as a seperate process from cupsd,
it's been running fine since early this morning.

Thanks,
