Thread:Project:Support desk/Maintenance error with APC enabled

Hi, I'm getting the following error trying to run the maintenance script runJobs.php with APC enabled:

CACHE_ACCEL requested but no suitable object cache is present. You may want to install APC. Backtrace:
 * 1) 0 [internal function]: ObjectCache::newAccelerator(Array)
 * 2) 1 /nfs/c02/h06/mnt/46267/domains/practicalplants.org/html/w/includes/objectcache/ObjectCache.php(62): call_user_func('ObjectCache::ne...', Array)

I get no such problem from the front-end wiki itsself, and I can see from my PHP info that APC is enabled. http://s46267.gridserver.com/gs-bin/phpinfo.php-stable shows:

APC Support	enabled Version	3.1.11 APC Debugging	Disabled MMAP Support	Enabled MMAP File Mask	no value Locking type	pthread mutex Locks Serialization Support	php Revision	$Revision: 325875 $ Build Date	Aug 13 2012 11:25:11

Directive	Local Value	Master Value apc.cache_by_default	On	On apc.canonicalize	On	On apc.coredump_unmap	Off	Off apc.enable_cli	Off	Off apc.enabled	On	On

Is this a problem you've encountered before? Any ideas what I can do to solve it, other than turning caching off?

Thanks, Andru
