apc backend uncaught exception "Could not set value"

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
Uncaught TYPO3 Exception: #1232986877: Could not set value. | t3lib_cache_Exception thrown in file (...)/t3lib/cache/backend/class.t3lib_cache_backend_apcbackend.php in line 131
(issue imported from #M17886)
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.
How to check: http://www.antusblog.de/2009/08/12/apc-status-und-uberwachung/
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.
- Target version deleted (
0)
Reason for this error is that apc.enable_cli is set to 0. The APC backend cannot be used on CLI in that case.

- Status changed from Under Review to Resolved
- % Done changed from 0 to 100
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
