Mac OS X - High CPU Usage

This happened to me yesterday (the Logos process went to 500%) and just happened again today. I don't know about yesterday, but today it was locked in a sync cycle. I had to force quit Logos.

I used the Logos Logging Utility to get a sample and archive while Logos was still running, but the Utility froze up also and I had to force quit it. The log sizes are smaller than normal:

4786.LogosLogs.levi.20130905-111413.zip

After force-quitting Logos, I archived the logs again:

I am on OS 10.8.4 with Logos 5.1a SR-1

We're currently having some trouble with Core Animation and the Sync arrows. Something is causing the animation of the arrows to use up large amounts of system resources. This occurs because we are basically checking the entire application for changes to animate, instead of the small arrows graphic, every time they spin around (about 30 times per second).

This has already been identified and will be resolved in version 5.1. For now, as a work around, you might want to use the application offline, then intentionally log in and sync it when you're done working. This will avoid the problem occurring 'at random' whenever we sync automatically.

Our apologies for the inconvenience.

I'm still experimenting to confirm (hard to confirm when system is totally locked up), but I may be experiencing the same issue on a PC.

See thread below for details.

Wow, I set "use internet" to "No" in the preferences and 2 minutes into the experiment my cpu usage spiked again. There are no arrows spinning and no indexing happening. 

It's pretty frustrating, as my computer slows to a crawl. Any advice on workarounds to make Logos usable again?

I restarted and still the same issues. Even restarted my computer.

Happening to me as well:

Logs attached.

I am not sure if I have high CPU usage, but my fans are spinning.... sounds like my laptop is going to take off. Whatever it is hopefully it gets fixed soon! [:@]

I am having this same problem.  A quick fix would be nice.  Any new information about that?

Tommy, this is not normal. I’ve used Logos since 2009, and this is something that just started happening in the last 2-3 months, first on OS 10.8 and now on OS 10.9. 

I keep a fairly close eye on my system using iStat menus, and Logos didn’t use CPU like this before (I am only using the CPU percentage as a comparison; Incidentally, I have four cores, not eight). More importantly, it didn’t get stuck on high usage to the point that the fans are screaming (an unusual event on an iMac, at least for me). And when this happens (a few times a week), it requires a force quit.

If you're using WiFi, switching to Ethernet networking, and/or resetting your router and modem may help as well.

In my office, I cannot switch my method of connecting to the internet (it’s wifi or nothing), although I can say that I haven’t experienced slow internet problems while this is happening. I have a stable and speedy connection. I have tested once turning off “Use Internet” in Logos, but the issue still happened. Shouldn’t that have kept it from happening?

Tommy Ball said:

Is this happening to you every time you attempt to quit the application? 

No, it doesn’t happen when I am trying to quit. It happens when I am trying to work! To be clear, Logos gets stuck on a high CPU usage, the fans kick up to an abnormal speed, and at that point, I have to force quit or it just keeps going like that.

Integ, What you've described above is exactly what I've been experiencing. I posted about a month ago and then was away from the forums for awhile. I posted my logs here today. I hope we get this fixed soon. 

Logos recommended I delete my application and then download a new one. Did that, worked like a charm the FIRST time (previous purchased finally downloaded). Purchased another item, now it won't download again - the MacBook Pro is about to take off as the fan speeds up - had to force quit. Downloaded app again (and again, etc.) after deleting the app - it only worked the first time.

Just received the Ethernet adapter to plug into my Thunderbolt port - still waiting (at least the fan has not started YET). Will let is spin and see if the new purchase is ready to download (a 55vol. set) - downloaded on my iPad without a problem. Well, the fan has begun again. Using the Ethernet did not solve the problem ... wait, wait, the fan actually stopped (it NEVER stops unless I force quit)... as is often the case once it goes into this mode, you can't access the home page... just spinning, spinning - the fan is back on! OK, that did it, have to turn off the internet access on the app and just use Logos until they get this fixed. I had to force quit again -fan was getting ready for another take off ("Logos Bible Software 5 (not responding)").

Logos has become almost unusable because of this issue--very frustrating. It has become progressively worse. I'm having to do most of my work off of the iOS app by necessity.

I don't know if I'm just lucky or if this is an important detail, but I had the high CPU usage problem repeatedly when I tried to use Logos in full screen mode; however, I haven't had it once if I leave the application running (visible or hidden) in a regular window.

Since upgrading to OSX 10.9 I've had nothing but trouble with High CPU utilization in a variety of scenarios. This application is really getting annoying in terms of Quality Control

Thanks for the suggestion; thought this might work after reading it - I also use two external monitors on my MPB ... moved Logos to the MPB and not on the external monitor, did not set it for full screen... I hear the fan running hard again. Looks like the suggestion does not work.

I now groan when I hear the fan running because that means my Logos is doing its thing. Will have to turn off the internet access and use the app. until they fix the problem. I can't even access my new purchases … it won't download. Thanks anyway for the suggestion.

Any fixes for this yet?

This works for me. After receiving several tips on this site and one from Logos, I "found" that following this method works (for me). I am using the latest OS from Apple (Mavericks).

1. Replace Logos Application (drag app into trash and empty it). Download newest.

2. Make sure you do NOT have have "Automatically Download Updates" on.

3. Make sure you are NOT using "Full Screen" - reduce for now (can after everything is downloaded and updated).

4. Use Ethernet connection, not wifi.

This works for me. I can't promise if it'll work for you - but I can quit Logos without it hanging, the fan no longer screams at me, etc. Three of the four suggestions came from this site and Logos. #2 is the only thing I added. Thanks everyone. Not sure why it works but I ain't complainin'

It is working!!! I have been using this method the last couple of days. Downloaded another book yesterday, indexed, etc. and w/o any problems. I would be curious to see if someone else had success following the same. Because of this (and a faster Mac), Logos for the FIRST TIME is quick, smooth and enjoyable. I use Logos for its resources but always found it cumbersome and slow but I am really enjoying it and using it as much as the competitor (which is super fast!).
