Problems with memcached and ntpd on CentOS -


we having problem virtual machine that's running our frontend website. once it's running fine, after reboot memcached going bonkers. happens put items in there set expire in 15 30 seconds, don't expire hour! after while data we're serving highly outdated.

we've been investigating issue bit , found during startup ntp changing clock a lot, putting hour forward.

we found memcached doesn't use system clock has it's own clock, once system clock changes , sets expiry in it's time, memcache hour behind , keep item hour.

we've swapped boot order of ntpd (now s58) , memcached (now s59), hasn't resolved issue.

restarting memcached manually after reboot not option because our host reboots server regularly after patches , we're not there after that's happened.

does have idea on how resolve this? we've googled high , low, can't find same problem. surely we're not first have problem?

virt-what reporting vps running in vmware.
