I guess my question is why did it withdraw the IP and then suddenly rejoin?

The mDNS package (multicastDNS) thinks you're disconnecting from the network and reconnecting again. If the rest of the your network services disappear for a short time as well, then you may have an intermittent cable problem. Try swapping out the cable and see if the problem goes away.

If the rest of your network services stay up while mDNS goes down, then it's just that one service. All I can think of in that regard is some kind of autoconfiguration process that is running periodically and it causes mDNS to shutdown and then come back up. I don't know what type of service it may be that does that, though. You could try Google'ing it and see what you get. Another (rather "overkill" technique) would be to turn on system accounting and the next time you see those messages in your log file check the accounting data and determine what was running during that time period.

Yet another technique (just as much overkill as the previous) would be to run strace -f on the mDNS service (add the timestamp option to strace; probably -t or -T) and then you can see what's happening inside the application by comparing timestamps with the next occurrence that appears in the log.

Warning: the strace option will create a HUGE amount of data! Especially if it takes hours or days before the entry is repeated in the log file.

/var/adm/messages vs /var/log/messages

The /var/adm/messages in Solaris seem to log more system messages/errors compared to /var/log/messages in Linux. I checked the log level in Linux and they seem OK. Is there any other log file that contains the messages or is it just that Linux doesn't log great many things?

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
