Redis out of memory, even with allkeys-lru policy

I have a Redis server with maxmemory 512MB and maxmemory-policy allkeys-lru but once the server has filled up after a day of usage, I can't add any more items:

redis 127.0.0.1:6379[3]> set foooo 123
(error) OOM command not allowed when used memory > 'maxmemory'.

IMHO that never should happen with the LRU policy.

I copied some server info to this Pasebin: http://pastebin.com/qkax4C7A

How can I solve this problem?

Note: I'm trying to use maxmemory because my Redis server is continously eating up memory even though nearly all keys have an expire setting and because FLUSHDB does not release system memory - perhaps this is related..

In the end I'm trying to use Redis as a cache.

Your info output suggests that a lot of your server's memory is taken by Lua scripts:

used_memory_lua:625938432

Note that Lua scripts remain in memory until the server is restarted or SCRIPT FLUSH is called. It would appear as if you're generating Lua scripts on the fly...
