8 years ago I agree that it seems weird that those negative times are logged. I need to
check what's happening there.
Besides this, do you experience unexpected behavior? Original comment by martin.grotzke on 22 Dec 2013 at 7:30

8 years ago This is my configuration in tomcat1.
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:192.168.1.110:11211,n2:192.168.1.110:11212,n3:192.168.1.110:11213"
failoverNodes="n1"
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
This is my configuration in nginx.

Besides this,I discover that the msm will be initialized one more times.The
following is a log.

Why the msm is initialized more than one time?
In addition,the logs also look like abnormal when I send a request to one of
the tomcat instances.The request also is handled more than one time.The
following is a log.

8 years ago Perhaps the duplicate log output is just a logging issue and misleading.
Do you experience unexpected behavior?Original comment by martin.grotzke on 1 Jan 2014 at 11:41

8 years ago I want to make clear the principle of 'failoverNodes' by source code, but the
repeated logs disrupted tracking process.
Now,I have 3 nodes,And this is the configuration of each node as follows.
<Context>
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:10.100.10.21:11211,n2:10.100.10.22:11211,n3:10.100.10.23:11211"
failoverNodes="n1"//In the node of IP 22 is n2 and In the node of IP 23 is n3
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
</Context>
I want to know that the session of node1 is a backup in which Memcache nodes,
and what is strategy.I did not find the details in the project document.I need
some help, thank you very much.Original comment by 150349...@qq.com on 2 Jan 2014 at 5:10

8 years ago You've configured failoverNodes correctly.
I just updated the documentation (SetupAndConfiguration):
> This attribute must contain the ids of the memcached nodes that must only be
used for session backup when none of the other memcached nodes are available.
Therefore, you should list those memcached nodes, that are running on the same
machine as this tomcat. E.g. if you have tomcat1 and memcached1 (n1) running on
host1, and tomcat2 and memcached2 (n2) on host2, then you set n1 as failover
node for tomcat1, so that tomcat1 does only store sessions in memcached1 if
memcached2 is not available (for tomcat2 failoverNodes would be set to n2).
With this setting host1 could completely crash and sessions from tomcat1 would
still be available.
Is this description more clear now?Original comment by martin.grotzke on 2 Jan 2014 at 8:28

8 years ago Your critical analysis helped me a great deal.But I still have some questions.
I did some testing before.In the above configuration, when 3 Tomcat and 3
memcached instances were normal,the session of tomcat1 will backup in the
memcached2,the session of tomcat2 will backup in the memcached3 and the session
of tomcat3 will backup in the memcached1.
When I killed the tomcat1,the request arrived tomcat2.Because the session of
tomcat1 was backup in the memcached2,the session will be acquired from
memcached2 and stored in the tomcat2.Now,the session only be stored in the
memcached2 and tomcat2.When the session is expired,the new session will be
created in tomcat2 and stored in the memcached3.
This is normal?

8 years ago Node selection for new sessions happens randomly, like
pickRandomFrom(memcachedNodes.subtract(failoverNodes)).
If a session after a tomcat failover is stored in a memcached node that is
configured as failoverNode this is an oversight and should be fixed. Can you
please verify this and submit a separate issue if it's reproducible?Original comment by martin.grotzke on 2 Jan 2014 at 7:02

8 years ago Now I have completely make clear the strategies for 'failoverNodes',and the
problem about that session only be stored in the tomcat2 and memcached2 before
can be reproduced, I will open a new separate issue.
Thanks to your help.But what about the negative memcachedExpirationTime?Original comment by 150349...@qq.com on 3 Jan 2014 at 5:01
GoogleCodeExporter
commented
8 years ago Thanx for submitting the issue!
I just checked the negative memcachedExpirationTime, and it was caused by
tomcats internal "processExpiresFrequency": tomcat doesn't expire() sessions as
soon as they reached their timeout, but they're expired according to the
configured processExpiresFrequency, which is 6 by default. Because tomcats
background process runs every 10 seconds, and processExpiresFrequency is 6 by
default, a session with timeout 5 minutes will be exipire'd 60 seconds after
the session reached its timeout.
This lead to the negative memcachedExpirationTime.
I just changed the expiration time that is set for sessions in memcached to
respect the offset caused by processExpiresFrequency so that msm should no
longer print any negative memcachedExpirationTime.Original comment by martin.grotzke on 3 Jan 2014 at 10:01
