enter image description hereAfter running top -o cpu

Im seeing 13 instances of Ruby near the top. They are only using a very small amount of CPU but I can't figure whats causing them to run?

iMac 4GB RAM OSx Lion.

Just ran f-secure flashBack checker and my iMac is apparently not infected. Also according to top _devicemgr is the user for the ruby processes

  • Is this a coding question or a systems question? Do you do ruby development and possibly created these processes yourself, or are you worried because you don't know how they could have been started? – Nate May 2 '12 at 13:27
  • Im not doing any Ruby development thats the thing. I don't know why there are so many processes running? – geminiCoder May 2 '12 at 14:15
  • any more details on the processes? is the name just ruby? You might try ps auxww |grep ruby to see if there are additional arguments to the commands – skarface May 4 '12 at 18:50
  • Not to be alarmist, but I think there's a variant of the Flashback malware about that has a Ruby payload. Of course you might just be running some app that uses Ruby. – AKX May 9 '12 at 13:00

If you search for the usernames that appear in your screenshot, you will find that they (e.g. _teamsserver) belong to certain OS X Lion server processes. For example, these are related to Wiki services.

Therefore, there's nothing to worry about. These are not malicious. And unless they're using up more CPU than you want, you can keep everything enabled.
