What do you mean by evictions? Cache misses? There are plenty of valid
reasons for cache misses that can change depending on the traffic coming
in rather than the state of the cache being full.
I am using version 1.1.13; the list of stats I see are pid, uptime,
time, version, pointer_size, rusage_user, rusage_system, curr_items,
total_items, bytes, curr_connections, total_connections,
connection_structures, cmd_get, cmd_set, get_hits, get_misses,
bytes_read, bytes_written, and limit_maxbytes. Which of these indicate
evictions (and what is an eviction, anyways? ;)
