I'm trying to setup clustering for my lifery 6.2 running on two JBoss 7.2. Both of my application servers use the same configuration but don't behave the same. One is starting and running fine, the other one crashes during startup. It's related to the cluster settings.
cluster.link.enabled=true
cluster.link.autodetect.address=10.170.121.184:1531
# second points to db server
As mentioned both servers use this setting. Once I remove those lines, the second server starts as well. But this would prevent me from using a clustered environment. I did some research in my logfiles and found several exceptions (during liferay deployment while server starts).
This is from liferays logfile. Not really exciting since it does not really provide valuable information.

I don't know why this liferay tries to open a connection to this IP, I don't know where this address is configured (never did this by myself), I don't know to which system this address belongs to (not an IP from my network) and I don't know why my other server (with same config) is not running into such problems. Maybe this address is some sort of default or fallback?
This behavior does not change when I start the troublesome server first or completely alone. This one always runs into the given problem.
I do have some additional ehcache settings referenced in portal-ext.properties to use unicasts instead of multicasts, but this config is the same for both servers too so the initial cause must be somewhere else. But maybe I could use these additional ehcache settings to adjust this IP?
I followed one of liferays blog entries to set up my environment. As of now my ehcache settings are the same as mentioned in this post (since my second server is not starting I cannot check whether I need some changes).
https://www.liferay.com/de/web/fimez/blog/-/blogs/configuring-a-liferay-cluster-and-make-it-use-unicast-
Does anyone have some expirience with setting up a liferay 6.2 cluster or maybe some insight on ehcache/jgroups settings that could turn out helpful? I'd really appreciate it.
I'm in a pretty similar scenario, using Liferay 6.2 running on two JBoss 6.3, and same as you "Both of my application servers use the same configuration but don't behave the same. One is starting and running fine, the other one crashes during startup."
After testing a lot of configurations, this one work for me, I removed this line from the server which runs into the given problem:
cluster.link.enabled=true
Leaving the line just in the server which is starting fine.
Surprisingly cluster configuration works very well.
PD. Sorry for my bad english.
Following must be the problem.....
Caused by: java.rmi.ConnectException: Connection refused to host: 15.131.81.31; nested exception is:
java.net.ConnectException: Connection timed out
This is maybe because of the firewall configuration. Or because of other network related causes... Or the expected service,- RMI serice is not running at 15.131.81.31
Once this is sorted out.... I hope you could come out of the problem....

From this link:
exception in GWT RPC app
Most likely cache has become corrupted for some reason, so try to
remove folder gwt-UnitCache from your project, this should help.
I have just published my first app today but for some reason when I use the published version I keep getting a ClassNotFoundException error when it starts up. It works fine when I test it in debug mode on my phone so I'm not sure whats causing this.

"Unknown database 'vision-mil2'."
It seems that database hasn't been created.
Make sure that database directory has not read-only permissions, and make sure that database is really created.
i have a strange problem. We have wrote a simple eclipse plugin to send email, we use javax.mail.
When we start the plugin from Eclipse it works and sends email, when we export the plugin and start it from eclipse.exe we receive this error

Try to run the application with disabled firewall.
You probably save the email settings somewhere.Check if they are saved correctly and if they are used properly in the code.
Have you tried the .exe on the same pc or on a different one ?
