Hi,

When I do 50 logins per minute (or more),

I get an OK response from my app, and the session saved locally on the tomcat server,

But, I also get an ERROR from the memcached (I attached it bellow)

I am using memcached-session-manager (version: 1.6.5) on a tomcat server (version 7.0.34) and java version 1.7.0_25,

And my app using spring security (version 3.1.0)

my memcached-session-manager configured to work with synchronic session backup as follows:

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"

memcachedNodes="sz-all.XXXX.XX.XXX.cache.amazonaws.com:11211"

requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"

sessionBackupAsync="false"

sticky="false"

copyCollectionsForSerialization="false" />

To my knowledge, synchronic session backup should prevent this problem,

And if there is a problem during the session backup Spring security should catch it during the login.

ERROR OUTPUT:
