eliminating memcached's 30-day limit

Question

Why does memcached impose a 30-day limit on the lifetime of cache entries?

In my system, I am always setting the lifetime to be 30 days, since that\'s the max allowe

Answer 1

30 days is the limit at which we consider the time you specified to be a TTL from now.

If you want longer than 30 days, it's fine, just use an absolute time (time() + whatever).

If you want no time-based expiration, as ConroyP says, just use 0.
