wp-now: out of memory error when running for many hours #96
Description
I often have wp-now running for days and after a while—I think usually > 48 hours—I get something like the following:
Fatal error: Out of memory (allocated 2097152) (tried to allocate 65536 bytes) in /var/www/html/wp-includes/rest-api/endpoints/class-wp-rest-controller.php on line 388
After that I can't recover the instance. I'm not sure what info I can provide to help illuminate the cause. I tracked down the debug.log in ~/.wp-now/… but not sure the output before the out of memory error is related.
debug.log portion

Anyway, it’s a pretty small bother given how quick it is to spin up another instance. Still I thought the report might be appreciated.
I love using this compared to wp-env. Awesome work on it!
