We have Openfire 3.7.1 running on Ubuntu 8.04 (Running on Vmware ESXi 4.1). The server was configured with 1G memory, now we increased the memory to 1.5G.
The number of users using the server is aproximately 250.
The** java memory** is set to: “-Xms512m -Xmx1024m”
The caches is configured as follows:
Once per day the server stops exchanging messages between clients (at least some of them) and refusing new login attempts (with the error “Invalid Username/Password”).
According to my observations so far it seems that something “is eating” java memory - the value that is visible through the admin console.
In the error.log we are observing the following errors:
org.jivesoftware.openfire.ldap.LdapGroupProvider - Groupname Co-worker not found
org.jivesoftware.openfire.ldap.LdapGroupProvider - Groupname General not found
org.jivesoftware.openfire.handler.IQHandler - Internal server error
It seems that these errors are coming from search of the personal groups ( configured on some client from ICQ, or other IM) in LDAP.
But i’m wondering could this search be the reason for memory leaks or something…?
