Hi. It just means your apps are fighting harder for real memory (the 1 or 2 GB used by the processor, not storage). Maybe you're viewing web pages with lots of decoration (ads). Maybe you're playing a game with intensive graphics, editing high-res photos, etc. These are just logs, not errors, and you should ignore them. Your device might run a little faster if you close (force quit) apps you're not using, especially memory-hungry ones.

These are logs. When you sync with iTunes it copies the logs onto the Mac/ PC. If these bother you disable the diagnostics logging…

Settings > Privacy > Diagnostics & Usage.


There is little to nothing you can do about these on iOS besides updating your iOS versions & updating any related apps, if you have crashes contact the relevant developer, then they may be able to use the logs.


JestamEvents appear to occur when memory is low (this is not the 'storage', this is RAM). They may simply be logged when the OS is doing what it needs to do.

I'm not sure you want to know the detail of jetsam events, you would have to read Apple developer documentation to get all the details but there are posts that try to explain it…

It is complex & can be normal this is why we need to know what problems you are actually seeing - e.g. If all apps are reloading when you open them (to the clean 'first launch state') maybe you need to reinstall the OS. Seeing jetsam logs is not a sign of anything in general.


'awdd' is also another log that is normal…

What does (awdd) mean

It is simply diagnostics that get sent to Apple to help with their own services.


You may just want to stop looking at logs - they are only useful if you know what you are looking at & are looking for specific problems.


Post a link to your new topic if you want us to follow you there.

Do you have a problem or are you simply assuming these messages are the problem?


Jestam events are how iOS is meant to work, as such you cannot stop them (which is probability why this thread is not solved after 2 years). Memory is limited on iOS so it will remove apps from memory as part of it's normal operation.


Your device is also not an iPad running iOS 8, so I can't really see how it is related to this old topic.


For the final time - if you have a problem explain what that is, ideally in your own topic or you can continue to post here & hope some has a better idea, but I don't think these messages are a sign of anything (maybe I am wrong, in which case please enlighten me).

I have no idea I do not work for Apple & do not represent Apple. I'm simply another Apple user just like you.

Hi. Regarding your iPhone 7 freezes, I suggest that you post in the Using iPhone forum (this is Using iPad). You may find other users with the problem over there. The jetsam events occur when the processor memory is almost full and apps are told to release any memory they can. You may be running an app that downloads a lot of data. Browsing websites with lots of ads can produce this. The log files are dated, so you can see if they seem to be linked to the freeze-ups.

I appreciate your help. I got to this page by searching Jetsamevents. I am new to the community,so please bear with me. I stop diagnostics reporting and went from getting an awdd everyday to all of these Jetsamevents. My real question was why this did this happen? And what was a Jetsamevents. I put up a snapshot but it might not be helpful. I will try to start a new di

Hi. Most devices get hot when charging. How hot is it? Warm like an electric blanket? Or too hot to touch? If it's too hot and you're using the original Apple charger, you may have a hardware problem. How old is your device? The "periodic" events are normal and occur periodically. The jetsam events occur when an app needs memory. This is often when Safari loads a page with lots of ads and other decoration. Also, as I suggested to kayihan, you should post in Using iPhone, where more iPhone users will see it. Be sure to identify your device model.
