memcached timeout error because of slow response

Hi, we expirience memcache slow responses. (rare, only 3..5x per 24h) I tracked the "mecache timeout errors" down to the following: 36278 13:52:46.020698 192.168.43.129 -> 192.168.43.133 MEMCACHE get key 36299 13:52:46.061557 192.168.43.133 -> 192.168.43.129 TCP memcache > 47127 [ACK] Seq=1 Ack=7

Gigs of swap being used, but why?

Hi :) We have a small farm of 8 memcached boxes (Dell R210s, Debian Lenny x64) with 8GB RAM. I've just noticed that a) there is swap configured on these machines (probably my bad) and b) many gigabytes of swap is being used. memcache09:~# ps faux USER PID %CPU %MEMVSZ RSS TTY ST

Re: Gigs of swap being used, but why?

The 'swappiness' proc knob was on its default of 60, but I just don't get it... the VIRT columns of all running process don't add up to anywhere near (physical RAM + swap in use) (they add to under 10GB) It can't even be disk cache because there's only 660MB in use on the rootfs... Filesystem

Re: Gigs of swap being used, but why?

Hi Brian, Thanks for that; I'll try pulling back the RAM usage on each instance a little to clear some more headroom, and disable swap on one of the mc nodes so I can monitor for OOM process kills. The RSS numbers still don't add up to the amount of swap being used, so I'm still curious about tha

Comment #7 on issue 158 by marcolslaviero: Single packet DoS on UDP channel http://code.google.com/p/memcached/issues/detail?id=158 Well spotted, I was indeed running the initial tests with -t 1. At least that clears up some minor confusion this side.
