express - What makes my information get deleted from `memcached` -


currently using memcached + connect-memcached + express-session have user information stored temporarily during lifecycle.

but found user information got delete fast have no idea why? happened following:

  1. login username , password, user info should stored 7 days due express-session config cookie: { maxage: 86400000 * 7 }
  2. after login, leave mouse , keyboard while(may 1 minute)
  3. try click on webpage requires user info
  4. while digging node code, have sessionid cause set in cookie, , memcached returned nothing key kill me.

i didn't find document behavior, can help?

i'd know why information deleted it's not expired?

i've given 2000 -m option memcached could't find documentation described it(i thought should memory usage).
