"OS X 10.9 Mavericks bug generates a lot of Internet traffic
Have you got to know already that Mavericks's "ocspd" process generates huge amounts of Internet traffic?
This process on my private MacBook Pro consumed up to 4 GB of traffic per day (!!!). The 6 Macs we use in our company downloaded between 189MB and 3,5GB per computer and per day. For my private MacBookPro alone this means up to 120 GB of traffic just caused by this bug. Here in Europe there are a lot of data plan limited ISP contracts and if you only have 10GB of traffic, you are done after 3 days without having used your Internet. Before I used Mavericks, my private download traffic was typically only around 20 GB per month.
There seems to be a workaround to stop this unintentional traffic of your computer by de-activating some options in the keychain. It seems to work at least for me and all the macs in my company. You can see this by using the net monitor function of Little Snitch. (OS X Activity Monitor can also show Network traffic stats (in/out) by Process.-Mike)
It seems Apple is working on the problem. I wonder why no web site has reported about this bug already. Wouldn't it be good to warn at least those users with a limited data plan?
Best regards, Stephan K."
Thanks Stephan. I have a mini w/10.9 installed on it, but rarely used (maybe 2hrs in the last month) and not checked for this but posting as a FYI. (Work iMac is running 10.6.8.)
