Bug Cache suddenly stopped working

[Bryan Choo]

hi, vboptimise is my fav mod and everything was working perfectly until recently. i did not change any of the settings and before coming here i also verified with my host who spent hours trying to figure out what was wrong (they said they didn't change anything on their server side)

Some information to help:

When i run the system test everything works except the t hird one where i get this error message for "fetch cache"
Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.

xcahce is enabled on my vps, i have chose that as my cache option and this is the config from the config file.

$config['Datastore']['class'] = 'vB_Datastore_XCache';
$i = 0;
// First Server
$i++;
$config['Misc']['memcacheserver'][$i]		= '127.0.0.1';
$config['Misc']['memcacheport'][$i]			= 11211;
$config['Misc']['memcachepersistent'][$i]	= true;
$config['Misc']['memcacheweight'][$i]		= 1;
$config['Misc']['memcachetimeout'][$i]		= 1;
$config['Misc']['memcacheretry_interval'][$i] = 15;

This is my phpinfo()

Well for one, you don't need the memcache information uncommented if you use XCache.

For two, it's likely your cache is full. Please install XCache-Admin on your server and check to make sure.

i have tried flushing cache does that do anything or shouild i get my host to install xcahce admin

 

[Fillip H.]

Should still install that to ensure there's no other problems with it.

 

[Bryan Choo]

Installed, here you go.

Anything you can read from it?

If we look at the var #0 and var #1 lines you'll see you have 48 and 336 bytes of space left in the cache. The 21k misses (a miss, if I'm not too mistaken, is an attempt to use cached data but none was found) is a result of there being way too little space left in the cache.

I would suggest you try setting xcache.size to 32M and xcache.var_size to 8M - then restart apache.

Afterwards, keep an eye on the Caches bit of the first image - once you see the OOMs (Out Of Memory) stop increasing, that's when you know you're safe. Until such a time, I suggest you double the two variables I mentioned earlier from my suggested values until the OOMs stay empty.

It may take a while before you start seeing OOMs again, so I would suggest checking back on either the vBO stats page or the XCache Admin page every few days to see that everything is still going smooth.

alright will try that.

btw how do i solve this problem?
Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.

It is unable to store data because it is out of memory

I'm unfortunately unable to assist any further with this, please contact your host and ask them to verify your php.ini settings for XCache. Tell them you have problems with it going out of memory.
