Q: Mavericks update, 10.9.3, your system is out of memory

Make sure there's enough storage space ..

Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage

Make sure there's at least 15% free disk space.

There may be a program running in the background that is chewing up memory.  First thing to check is what starts when you log in under your user account.  Second thing to check are the log files.  Are there repetitive enteries every second?

Have a nice day.

I had the same issue happen today. This happened twice with Safari v7.0.3 and Adobe Flash v13.0.0.214 while using Spotify for Web. I attempted to use Spotify for Web using Google Chrome v34.0.1847.137 and Adobe Flash v13,0,0,214 and did not experience the issue. I tried Safari again, same problem, In about 5 minutes my system prompted - Out of Memory.

*note - My machine has 156GB of available free storage space on the system disk.

Mac Mini - Late 2012

16GB Ram with 256 SSD.

"your system is out of memory."

Out of application memory?

Yes, application memory.

Hi there, so I am curious? Last week I bought a brand new imac with 24 gb ram and 256 SSD drive. And I only intalled CS6. Nothing else. On day 6 I already have the "system runs out of application memory" issue..just running Safari. This must be a joke...no? Do you think I should give the imac back to the apple store or is there hope that this issue is resolvable?

I have the very same problem with 16GB of memory on my iMac and Yosemite OS. Never happened before.

I also checked overall free space on my drive - 750GB free on a 1TB drive.  It must be a glitch in Yosemite. Hope they fix this!!

This is not a System problem, it is a problem with the configuration of one of the Applications you are running.

Use Activity Monitor's Memory pane to find out more about who is swallowing the memory:

OS X Mavericks: About Activity Monitor

Hi,

I have checked it shows under memory my 'syslogagent' is running at 1.64

Let me know if anyone has any suggestions. It keeps popping up "your application memory has run out"

None of these pages tell me how to OPEN activity monitor to begin with. When I search for it in Spotlight, nothing appears. Can't find it in system preferences either. Last night I had to reinstall Mavericks and abandon Yosemite because Mail ceased to even open with the latest OS.

Applications/Utilities/Activity Monitor.

Thanks much.

Mac Mail stopped working entirely for me with Yosemite. Tried re-starting, etc, no avail. Had to go back to Mavericks, which my iMac appears to like a lot better. Everything opens faster, etc. Not what I would have expected...

BTW, the biggest 'memory user' according to Activity Monitor is something called 'kernel_task', using 1.06 GB. Have no idea what that is. Next biggest is Firefox at 540 megs.

Thanks again...
