Hello!
The fact that the server is working and there is a constant exchange with
memcached operating sites and calmly execute commands and remove accurate
statistics in moments when it is clear the cache - is problematic These are
additional information:
1. Separately when I run a copy of memcached on port 12212 and check there
work test script - all is normal, the data from the cache, and are given no
fresh values in the cache, i.e. it clean from sites scripts?
2. Concluded memcached information about working in a file and there can be
large log to find if an error "Fresh Data:":
--------------------------------
42: going from conn_closing to conn_closed
<42 new auto-negotiating client connection
42: going from conn_new_cmd to conn_waiting
42: going from conn_waiting to conn_read
42: going from conn_read to conn_parse_cmd
42: Client using the ascii protocol
<42 get data
> NOT FOUND data
>42 END
42: going from conn_parse_cmd to conn_mwrite
42: going from conn_mwrite to conn_new_cmd
42: going from conn_new_cmd to conn_waiting
42: going from conn_waiting to conn_read
42: going from conn_read to conn_parse_cmd
<42 set data 1 3600 45
42: going from conn_parse_cmd to conn_nread

42: going from conn_nread to conn_write
42: going from conn_write to conn_new_cmd
42: going from conn_new_cmd to conn_waiting
42: going from conn_waiting to conn_read
42: going from conn_read to conn_parse_cmd
<42 get data

>42 sending key data
>42 END
--------------------------------
it turns out that the data "data" are simply lost in the cache?
3. Possible at this moment to get statistics ("stats" command) and output
its in the log to then show you here? Because if everything is in the
terminal (telnet. ..) it will be a lot of lines and it is impossible to
have time to fix their exchange data from the cache is constantly on sites
