Q: IMRemoteURLConnectionAgent taking up CPU

I need some help figuring out what to do with a process that has taken over the CPU. The computer is a brand new iMac (Retina 4K, 21.5 inch, Late 2015). 3.3 GHz Intel Core I7. Actually right now I have 3 computers with this same problem.

There is a process in Activity Monitor called IMRemoteURLConnection Agent that is taking up anywhere from 70 to 95% of the CPU. I have done a call with Apple already and first off they had never even heard of this process. After a while they figured it was related to Messages. They said it is constantly pinging the Cloud for contacts in Messages. They thought there might have been a bad golden image and had me create a new bootable disc with the latest version and install that on the computers. It doesn't help at all. It's still taking up all the CPU. There is nobody even logged into Messages. I've tried doing pram and safe boots which takes care of the issues for a few hours. Then it comes back. Has anybody had this problem and how can you fix it?

iMac, OS X El Capitan (10.11.5)

    Hi Linc and Dianefromeb,

     

    It does seem odd.

     

    IMRemoteURLConnectionAgent does start up during the Start up process but does require the Mac User Account  has iMessages set up already.

     

    As the Guest account picture says the account has been running for two hours it does not seem it has been a fresh Start of the Account.

     

    In the Second and Third pictures the PID number (Process Identification Numbers) have numbers in the 5 digits range and I think I can read at 76,000+ in several.

     

    I would Shut Down the computer and on Start Up choose the Guest account.

     

    I have just started my computer  and this in my Screen Grab

    The Finder (effectively the point where the Desktop is complete) is at  361 near the bottom of the grab.

    IMRemoteURLConnectionAgent is at  422

    Firefox which I always launch first is at 755 (out of sight in this pic)

     

    At the time of writing this I have had my computer on for about 3/4 hour and some of the figures in the CPU time column don't seem to reflect that (maybe it is total core(s) time.)

    You guys are awesome. I think this might be it. I disconnected the ethernet and put it on public wifi. It is now at 0.0 on the guest account, the admin account and my own account. I have two computers I've been going back and forth on so I'll shut them down for the night and redo the tests tomorrow.

    Good grief what if it's our own network messing with them and why only the new ones.

    Apparently your network is blocking something that shouldn't be blocked. The firewall logs may be helpful. See also below.

    We're seeing the same thing here, when our users are connected to our internal WiFi (and possibly the wired Ethernet too, though hard to say as most of them are wireless only with MacBooks).  It seems to be related to our proxy server (WebSense) that is blocking whatever this IMRemoteURLConnectionAgent is trying to get to.  I have an AppleCare case opened, and they seem to think it may be a known issue that is being worked on, with regards to a bug in that component, and specifically when the proxy server supports "Negotiate" authentication in addition to NTLM or others.

     

    We were able to improve the situation in a short test by explicitly defining the proxy server settings for HTTP and HTTPS connections in the Network Preferences window.  The 60-75% CPU immediately dropped to almost 0 once the proxy was explicitly defined.
