Bug xCache var grow and grow with 1024MB of size

[dbembibre]

have a strange problem, xcache grow and grow, and never stop. And i see out of memory exception. I dont have xcache auth enabled, and the system test of vboptimise work ok.

What's the problem ??
I can set 2048MB to var size but i guess that the problem is not related with the size.



My settings are:

[xcache.admin]
xcache.admin.user = "admin"
xcache.admin.enable_auth = Off

[xcache]
xcache.shm_scheme = "mmap"
xcache.size = 128M
xcache.count = 4
xcache.slots = 8K
xcache.ttl   = 7200
xcache.gc_interval = 3600
xcache.var_size  = 1024M
xcache.var_count = 4
xcache.var_slots = 8K
xcache.var_ttl   = 3600            
xcache.var_maxttl   = 7200          
xcache.var_gc_interval = 300
xcache.test =                Off
xcache.readonly_protection = Off
xcache.mmap_path = "/tmp/xcache.xxx"
xcache.cacher = On
xcache.optimizer = On
xcache.stat   = On

If your forum is very large, or you have lots of forums putting data in the same cache, that's perfectly normal

You could try clearing the vars from that admin page though, see if that helps.

Yes i know that the disk cache take more size than the memory cache, but if i enabled memcached, all the forum is contained in 100MB and with xcache (yes i have in mind serialization) take more than 1GB. In other way memcached take 100MB included the network connections (that take memory too). Is a bigger diference for me.
I have $config['Datastore']['class'] = 'vB_Datastore_XCache'; in config.php what do you recommend about this ? keep uncommented or comment this line ??

Thanks

I don't think it'll make much of a difference what you pick. If memcached works better for you though, you could always stick to that

in my testing xcache with a 360 maxttl worked best. memcache can actually be slower if you only have one web server.

Yes tavenger, i move to xcache because is faster.
My config

[xcache]
xcache.shm_scheme = "mmap"

xcache.var_size = 1800M
xcache.var_count = 4
xcache.var_slots = 8K
xcache.var_ttl = 3600
xcache.var_maxttl = 7200
xcache.var_gc_interval = 300
xcache.test = Off
xcache.readonly_protection = Off
xcache.mmap_path = "/tmp/xcache.xxx"
xcache.cacher = On
