Your ps output says that the process is waiting on the physio routine. That means it is doing a read or a write to disk and is waiting for it to complete. Unix will not allow the process to die until the i/o completes. This is how it fulfills its promise of atomic disk i/o. I would suspect a hardware error in combination with a disk driver with poor error handling. The other possibility is a pathetic disk driver.

ZNEW(1) 						    BSD General Commands Manual 						   ZNEW(1)

NAME
znew -- convert compressed files to gzipped files SYNOPSIS
znew [-ftv9K] file ... DESCRIPTION
The znew utility uncompresses files compressed by compress(1) and recompresses them with gzip(1). The options are as follows: -f Overwrite existing '.gz' files. Unless this option is specified, znew refuses to overwrite existing files. -t Test integrity of the gzipped file before deleting the original file. If the integrity check fails, the original '.Z' file is not removed. -v Print a report specifying the achieved compression ratios. -9 Use the -9 mode of gzip(1), achieving better compression at the cost of slower execution. -K Keep the original '.Z' file if it uses less disk blocks than the gzipped one. A disk block is 1024 bytes. SEE ALSO
gzip(1) CAVEATS
The znew utility tries to maintain the file mode of the original file. If the original file is not writable, it is not able to do that and znew will print a warning. BSD
