After installing and enabling APC 3.1.9 (Alternate PHP Cache), using
pecl, i ran into an internal server error. I checked my error logs, and this is what shows up.
PHP Fatal error: PHP Startup: apc_mmap: mkstemp on /tmp/apc.efdb4d failed: in Unknown on line 0 [Wed Jul 06 23:47:41 2011] [error] mod_fcgid: process /var/www/cgi-bin/cgi_wrapper/cgi_wrapper(22397) exit(communication error), get unexpected signal 11
Instead of adding the APC extension to my
php.ini file, i created an
apc.ini file in
/etc/php.d/, here's my current APC configuration
; /etc/php.d/apc.ini extension = apc.so apc.enabled = 1 apc.shm_segments = 1 apc.shm_size = 128M apc.optimization = 0 apc.num_files_hint = 4096 apc.ttl = 7200 apc.user_ttl = 7200 apc.gc_ttl = 0 apc.cache_by_default = 1 apc.filters = "" apc.mmap_file_mask = "/tmp/apc.XXXXXX" apc.slam_defense = 0 apc.file_update_protection = 2 apc.enable_cli = 0 apc.max_file_size = 10M apc.stat = 1 apc.write_lock = 1 apc.report_autofilter = 0 apc.include_once_override = 0 ;apc.rfc1867 = 0 ;apc.rfc1867_prefix = "upload_" ;apc.rfc1867_name = "APC_UPLOAD_PROGRESS" ;apc.rfc1867_freq = 0 apc.localcache = 0 apc.localcache.size = 512 apc.coredump_unmap = 0 apc.stat_ctime = 0
Even after disabling APC, i ran into another error while trying to log in to Plesk CP:
ERROR: Zend_Db_Statement_Exception SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp/#sql_6d7_0.MYI' (Errcode: 13)
I fixed the above problem by restarting my container through Plesk's Power Panel. I think it had to with changing
mount -o remount,exec /tmp to solve permission errors during the APC installation through
pecl. After the installation was done, I returned
/tmp back to
noexec. The gist of these steps can be found here.
The first error still remains unsolved.
I'm Currently running on:
- CentOS 5.6
- PHP 5.3.5
- Installed APC 3.1.9
I'm not sure how to solve this problem. Is it because im using the lastest version of APC? or the
apc.ini config? Does it matter where i enabled the apc extension? i.e.
How about FastCGI and APC compability issues?
Any help or advice would be greatly appreciated.
