I am running PHP 5.6 and enabled the compiled-in module opcache. Now when I read the warnings inside my error log, I get these messages every few milliseconds:
Warning Interned String buffer overflow
So, to my understanding it is absolutely okay if cache gets exhausted and will be reused/recycled for new strings. If not, what am I missing?
opcache.interned_string_buffer from 4 to 8 MiB, but no luck yet.
