apc backend uncaught exception "Could not set value"
100%
Description
Ever since I've been using the apc caching backend, I get error reports about twice a day, notifying me of an uncaught exception "Could not set value".
I have not noticed any negative effects on the site functionality or received any complaints from users.
Extension: Core: Exception handler (WEB)
Severity: 4

Did you have a look at the memory usage? I had an error with not enough memory set for apc, but don't remember the exact message. Only happened on a Debian server, not on my local OSX setup, so maybe it also depends on your apc version.

I did check that, but could find no clues to the origin of the error. I have assigned 256 megabytes of memory to apc and it is by far not used up.
In either case, since this does not seem to cause a fatal error in the frontend, I think Typo3 should catch the exception and handle it as severity 3.

Reason for this error is that apc.enable_cli is set to 0. The APC backend cannot be used on CLI in that case.

I still get the "Could not set value" error.
I have the following APC options:
apc.enabled=1 apc.shm_segments=1 apc.shm_size=128M apc.stat=0 apc.canonicalize=1 apc.filters="-typo3temp/.*,-/usr/share/phpmyadmin/.*"
And I tried apc.enable_cli = 1 and = 0
Setting up those values in /etc/php5/conf.d20-apc.ini or in /etc/php5/fpm/php.ini make no sense.
I run Typo3 6.2.4 with nginx 1.2.1 and php5-fpm and APC 3.1.13
