In php-fpm.conf I have:
rlimit_files = 8192
My server is a 1G SmartMachine from Joyent, meaning it is a Solaris with 1GB memory.
My problem is that on high load I get errors like this:
Warning (2): touch() [function.touch]: Unable to create file app/tmp/cache/persistent/cake_core_users_da because Too many open files in [cake/libs/file.php, line 125]
Is my rlimit_files too low, and if so how high should I set it?
