It's unusually the question I mentioned in the topic. And, I can NOT find the offical answer from wiki.
Sometime, I set the expire time as '86400 * 24 * 4', the func memcached->set will return true, bug false when get.
I have tested the max expire time, the result is 86400 * 24 * 1.25, in others words: 30 days.
So what about the max time in your server? Does it relations to the hardware or it's own version?
My OS & env Info:
Dell PE R610
Intel(R) Xeon(R) CPU E5504 @ 2.00GHz * 2
16G memory
Linux mdev 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
Memcached ver: 1.0.1
Best regards.
