why is my iMac uploading to store-011.blobstore.apple.com ??

Question

why is my iMac uploading to store-011.blobstore.apple.com ??

Hello everyone,

for a few weeks now I've noticed horrible internet connectivity speeds from my iMac and all other devices on my LAN. As soon as I turn my iMac off or simply disconnect it from the LAN everything works fine.

I installed Little Snitch to see what is happening and found a (maybe even THE) culprit :

nsurlsessiond is uploading to store-011.blobstore.apple.com ... continuously ... with the maximum bandwidth my DSL will provide at any given time, essentially blocking all other traffic and requests or rather making them time out.

What is store-011.blobstore.apple.com and why is my iMac uploading obvious large data quantities there ?

iMac (24 inch, early 2009)

3,06 GHz Core2Duo

8 GB RAM

OS X El Capitan 10.11.6

iMac, OS X El Capitan (10.11.6)

Hi airbusdriverlt,

It sounds like you maybe having an issue with a runaway process on your iMac. I am not too sure what the "011.blobstore.apple.com" is, however, using the Activity Monitor, you should be able to end this process and reclaim the normal internet connectivity speeds. Please use the links below to learn how Activity Monitor can help.

Apps can affect Mac performance, battery runtime, temperature, and fan activity

Quitting the processes in Activity Monitor that are using high amounts of your network bandwidth should have this resolved ASAP for you. Thanks for using Apple Support Communities to post your question. Have a great day.

Hi JayB.

well, the application is nsurlsessiond not 011.blobstore.apple.com. Checking with search engines it seems that 011.blobstore.apple.com is a repository for iTunes U which I don't use. Second result seems to be that Photos uses this repository too.

That is a great way to find which apps are using this process, airbusdriverlt. If the processes cannot be ended using the Activity Monitor, try booting the iMac up into safe mode and then re-check the processes. OS X El Capitan: Start up in safe mode

If the processes do not seem to be consuming the same amount of network percentage, then restart the iMac normally. You can also try resetting the NVRAM. How to Reset NVRAM on your Mac

As a last resort if none of the above does not resolve, reinstalling OS X can prove to be beneficial. You can use Time Machine to back up your device before reinstalling. Please see the links below for further assistance.

Are you using iCloud to store photos? I just moved some pictures around on my iCloud account, and for the past 1/2 hour Little Snitch is showing a boat-load of data being uploaded to a similar site. As I monitored it, my upload rate dropped to zero just as the progress icon on my iCloud Drive showed that it was done.

are you running Kaspersky? this appears to be related to this application. no solution as of yet, other than to stop the program. would appreciate input if someone has fixed this.

Uninstall Kapersky. Its tends to interfere with the computer's operation while providing minimal to no benefit.
