I have a multisite blog and the cache is quite large due to the number of traffic and contents.
I have been facing the error in Nginx as below:
And changing the Nginx
fastcgi_buffers
andfastcgi_buffer_size
does not seems to solve the issue. Hence, I went deep into the plugin to see where does this came from.Apparently, on the request to "Purge Entire Cache", the GET request execute the
purge_all
method inFastCGI_Purger class
. Then, in that method is runs$this->unlink_recursive()
. This seems to produce huge response buffer.I decided to offload that process to Cron, using
wp_schedule_single_event
.
