How to clear APC cache without Apache crashes?

Question

If APC stores many records, clearing them will cause httpd to fail.

If apc_clear_cache ("user") takes longer than phps max_execution_time script call apc_clear_cache will be completed by php before the cleanup operation is completed. it seems to leave some pens or sth. which will prevent apache from closing it is being processed.

Is there any other quick but safe way to bulk clear the APC cache?

Answer 1

You can remove the time limit on the script that you are using (until you run php in safe mode)

set_time_limit(0); 

This will remove the time limit for the script

Answer 2

You can also gracefully restart apache and reboot with clean APC.
