What version of the product are you using? On what operating system?
2.6 , 2.10.4 (centos,fedora)
Tell me more...
spy memcache throws error "object too large for cache" in case of object size
is large. besides, it closing and reconnects the memcache connection. which i
guess should not be like that.
In case of high loads, this closing and reopening connection throws Timeout
exceptions of other async get calls.
