Can you telnet to the instances, type "stats", "stats items", and "stats slabs", then copy/paste all that into pastebin?
echo "stats" | nc host 11211 >> stats.txt works too You version is very old... It's missing many statistical counters that could help us diagnose a problem. The extendedstats isn't printing an evictions counter, but I can't remember if that version even had one. Can you describe your problem in more detail? If I recall: - User logs in. - Clicks somewhere. now they're logged out? - They click somewhere else, and they're logged in again? Does this mean they found their original session again, or did you app log them in again? -Dormando On Fri, 12 Mar 2010, TheOnly92 wrote: > I'm retrieving statistics via Memcache::extendedStats function, here > are the basics: > > Session Server 1 > Version 1.2.2 > Uptime 398,954 sec > Cache Hits 2,065,061 > Cache Misses 987,726 (47.83%) > Current Items 381,928 > Data Read 4,318,055.02 KB > Data Written 2,011,004.09 KB > Current Storage 100,688.96 KB > Maximum Storage 256.00 MB > Current Connections 9 > Total Connections 5,278,414 > Session Server 2 > Version 1.2.2 > Uptime 398,943 sec > Cache Hits 2,225,697 > Cache Misses 987,733 (44.38%) > Current Items 381,919 > Data Read 4,323,893.05 KB > Data Written 2,159,309.95 KB > Current Storage 100,685.52 KB > Maximum Storage 256.00 MB > Current Connections 11 > Total Connections 5,278,282 > > We are absolutely sure that both webservers are able to access the > memcache server instances, we selected memcache because it was an easy > configuration and setup without any changes of source code required, > not to think that it is "absolutely" reliable.
