Question Out of memory class_operator_memcache.php

[tavenger5]

I'm getting this error ramdomly throughout the day:

PHP Fatal error:  Out of memory (allocated 227278848) (tried to allocate 4438368 bytes) in /home/site/public_html/vboptimise/core/class_operator_memcache.php on line 66

I assume it is only happening when a large amount of data is being written into the cache. Short of increasing the php memory is there anything else I can do?

 

[Fillip H.]

I dont believe there's anything other than that you could do, no.

I didn't think so - I increased the php memory from 256 to 512. I'll have to see how that works out.

I ended up increasing to 1gb and I'm still getting the errors. It looks like with each instance it's trying to store something from the CMS in the cache and the cache can't handle it. I did a full stack trace:

That could happen to any script, it's just chance it happened to be a vBO page. But you can try turning off the CMS cache in vB Optimise to stop it happening on that particular page, though.

Out of curiosity, do you use the CMS for a large amount of content?

 

[tavenger5]

The largest CMS page is probably one like this under the review section: Motorola Droid Bionic Review - Cell Phone Forums

oh I just realized I read that wrong - there's about 2500 imported articles in the CMS. In some cases there are a lot of comments too.
