In addition i would like to know where can I set java hive size memory on openfire3.3.1

This sounds like a /etc/security/limits.conf issue for max file handles. Have you tried increasing that setting if the server is running as a non-root account?

Re memory: You can set something like this:

OPENFIRE_OPTS="-Xms256m -Xmx512m"

in /etc/sysconfig/openfire



Thank you your help, _However I have still got the same problem (busy at 943 users connection with 412.51 MB

of 2588.5 MB Java Memory)._

I have upgraded to openfire3.1.1 on Linux Read Hat Enterprise 4 with 4 GB RAM and set

-Xms512m -Xmx2688m using MySql 5.0.37 Community the database cction setting

minimum 5, maximum 50.

The etc/security/limits.conf

  •         -       maxlogins          6000

user_a - maxlogins 6000

user_b - maxlogins 6000

@jive - maxlogins 6000

  1. End of file

I’'m not sure about the setting limits.conf is correct or not. Do I have to setup more setting on linux

or openfire.

In addition, I try to use openfire3.3.1 on windows 2003 server with RAM 4 GB. I can setup java size -Xmx 1624MB If I set more than this the sevice is not able to start.

For the Utilize openfire3.3.1 on windows2003 server, the openfire serve on 250 users connection with 55.2%

of Java hive size memory ( 861.69 MB of 1560.00 MB )

Please Help me to solve the problem.

Best Regards,


hi napon,

I am not sure why you are setting maxlogins in /etc/security/limits.conf, you should set nofile like so:

daemon soft nofile 4096

daemon hard nofile 131072

Where daemon is the user that openfire is running as…
