hi,all

i encounter a strange cache mis behavior~

i have 30 servers running ats(v6.1.1),  it running well for most of the time in 
the past,

but 4 of these servers suddenly suffer from cache miss these days, and i found 
only one particular request can't be cached (previously cached properly~)


the other servers still running well,

differences between these 4 servers and others:  that these 4 servers's load 
triple higher than others ( tps around 500-800, bandiwdth around 200mbit/s)


info about the request subdenly can't be cached: body size : 500K,  tps for 
this requests is around 60,


the only way i can get the response cached is restart ats and clear cache 
storage, but the problem reoccur agin for some time..

proxy.config.cache.ram_cache.size 104857600
proxy.config.cache.target_fragment_size 16384
proxy.config.cache.max_doc_size 15728640
proxy.config.cache.min_average_object_size 4096
proxy.config.cache.hit_evacuate_size_limit 0
proxy.config.cache.force_sector_size 0
proxy.config.cache.alt_rewrite_max_size 4096
proxy.config.ssl.session_cache.size 102400


i don't known what's the problem , any help will be appreciated.
