Now every time I flush I get:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 6291456 bytes) in C:\WINDOWS\Temp\silverstripe-cacheC--xampp-htdocs-silverstripe\cache.php on line 4

The flush seems to work though

Looks like the page you're loading is using more memory that you've set; just increase this until a future release with improved memory overhead arrives.

I had the same error, then I tried with 48, 90, 120, and 180M of memory limit.. still not workiing!
Is it impossible to use SS 2.2.0 by now ?

haagen can you please explain exactly what you were doing, as you've clearly hit a bug there we need to squash.

I'm having this problem too when do a flush. Even though I set memory_limit up to 64M in php.ini and restart apache, this problem still exists.

My page is just demo page installed by default. My development platform is on windows using the WAMP all-in-one package.

ps I can't make a flush to reflect my changes in template file.

Getting same error, I don't really want to set my limt above 64 megs.

It happened after I uploaded a new image for an asset.

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 68122 bytes) in /home/nate/domains/bassdrop.co.nz/public_html/sapphire/core/Requirements.php on line 159

Any fix for this?

Okay, so I see its a feature-lock for 2.2.3. Good.

For now I can increase my mem limit, but as is said in the bug comments, the assets folder only has a moderate number of images and this is only going to increase.

Looking forward to the next release more than ever now!
