Description
This is probably more of a memcache issue than an issue with the module, but I'll ask anyway...
Our stats are showing:
Free: 8.0 GBytes (99.9%)
Used: 8.6 MBytes (0.1%)
Hits: 516570 (30.2%)
Misses: 1196627 (69.8%)
Is there any known cause for memcache to have a miss percentage this high?
Thanks.

It depends on what you're caching and how long your cache has been running. You're only going to get hits if you request something that you've already cached. If you recently restarted the cache, expect your miss rate to be low for a while as the cache gets repopulated. The other potential issue is that you're cache bin is not big enough and so data is being deleted before it can be used -- to see if this is happening look at your "evictions" total. You want it to be 0.
