Apache 2.2 - CloudLinux 6.4 64bit - cPanel Varnish Nginx Plugin - PHP CGI/FastCGI

Infomration PHP info: /http://hostjp.net/test.php

I get error xcache from my website.

[10-Jun-2013 13:10:34 Asia/Ho_Chi_Minh] PHP Fatal error:  Cannot open or create file set by xcache.mmap_path, check the path permission or check xcache.size/var_size against system limitation in Unknown on line 0
[10-Jun-2013 13:10:34 Asia/Ho_Chi_Minh] PHP Fatal error:  XCache: Cannot create shm in Unknown on line 0

Setting xcache in php.ini current:

xcache.admin.enable_auth="on"
xcache.admin.pass=""
xcache.admin.user="mOo"
xcache.cacher="On"
xcache.coredump_directory=""
xcache.count="6"
xcache.coveragedump_directory="/tmp/pcov/"
xcache.coverager="On"
xcache.gc_interval="0"
xcache.mmap_path="/tmp/xcache/"
xcache.optimizer="Off"
xcache.readonly_protection="On"
xcache.size="256M"
xcache.stat="Off"
xcache.shm_scheme = "mmap"
xcache.slots="8K"

xcache.var_gc_interval="300"
xcache.var_maxttl="0"

Hello

I have moved this thread over to the Optimization forum. As for the error message, I notice the following path related to the error message:

xcache.mmap_path="/tmp/xcache/"

Have you checked to make sure your /tmp partition is not full, and uses the correct permissions (1777)? EX:

# df -h
# df -i
# stat /tmp

Thank you.

The permissions on your /tmp partition are normal. Did you run "df -i" to see if your /tmp partition was close to it's inodes limit?

Thank you.

I did find a similar question asked on the Lighttpd support website:

#15 (pcode cache does not work)

You may want to ask your question there as you are using a custom Varnish configuration that is not native to cPanel. Thus, there may not be many users on the cPanel forums using the same setup.

Thank you.
