Multiple bzcat processes

Oct 2008 20" Intel iMac running 10.6.8 with 6 GB of memory.


Memory had filled up recently -- due to Firefox, of course! Was down to 35 MB free out of 6 GB.


After quitting FF (which took a few minutes) I noticed several bzcat processes, each using about 25% - 30% CPU. Initially the kernel was taking up maybe 70% CPU. Quit all apps. Still had the bzcat processes running. CPU was maxed out at some point (at least during FF shutdown). Rebooted. Fixed. Any idea what this is? See attached screenshot.


I don't know if this is related, but I'm also haveing trouble with Time Machine backups taking over an hour (I have a separate discussion thread on that: https://discussions.apple.com/thread/5179086?answerId=22528453022#22528453022).

Time machine backups take way too long

I found the problem. Time Machine Buddy broke, and seems to have created the following processes:
