Out of Memory when deleting cache.

Actually clearing cache just renames the folder which is /wp-content/cache/all to /wp-content/cache/tmpWpfc. In this case, there is no need memory.

You see this error when you click on delete cache all button?

yes, we encountered memory issue when deleting cache using the button, but not all the times.

the issue might be in deleting files in tmpWpfc?

No it is not possible because 500 files are deleted every 5 minute via cronjob.

what will happen if we clear cache again even if tmpWpfc is not yet empty?

/wp-content/cache/all is conterted to /wp-content/cache/tmpWpfc/635876765

we observed this when we delete cache 3 or 4 times in an interval of few minutes, we have 500+ online users when doing this.

what will happen to the 3rd cache and so on?
how is folder /tmpWpfc/635876765 named?

thanks Emre.

what will happen to the 3rd cache and so on?

I couldn’t understand the question.

how is folder /tmpWpfc/635876765 named?

“/cache/tmpWpfc/”.time()

typo error… i mean on the 3rd cache deletion….but its now clear with .time()… thanks…

can we edit cronjob “500 files/5 minute”?

Now I got it ?? Please read the tutorial.

when updating a post, is it necessary to “delete all cache”?
is it possible just to delete one post?

thanks

i mean is it possible just to delete the cache for a specific post?

you can use “singleDeleteCache” intead of “deleteCache”

how about when updating a post?

singleDeleteCache() works when a post is updated.
