lsof output

what does this line of output signify from the lsof output:
java 1419 root 7u sock 0,0 2170 can't identify protocol

Thanks

That string does not appear in the SunOS 5.6 executable nor in the source code for lsof on HP-UX.

What version of unix are you using? What version of lsof?

Also check the FAQ on lsof. Search for "can't identify protocol" or "10.2.2" in Sunsite.ualberta.ca - Mirror LSOF FAQ.

Note that this is a FAQ for lsof - not specific to Solaris.
