Unable to create new UI sessions

Troubleshooting


Problem

Users cannot log in and SystemOut.log shows message - Unable to create new UI sessions because the number of existing UI sessions is at maximum capacity. Viewing the MAXSESSION table shows it has fewer records than value of system property mxe.webclient.maxuisessions

Resolving The Problem

mxe.webclient.maxuisessions is not related directly to the MAXSESSION table.
It is used to set the limit of how many UI sessions can be established in a JVM to prevent out of memory errors. The information is printed out in the maximo log by default. There is no back end database table associated with it since this is totally in the memory of the JVM.
WebClient sessions will on most systems be higher than the number of entries in the MAXSESSION table, especially when users have multiple tabs or multiple windows open.
To see the number of UI sessions, look at the end of the current SystemOut log for message BMXAA6369I with text similar to this example -
BMXAA6369I - Server host: xxx.xxx.xx.xxx. Server Name MXServer. Number of Users: 1 WebClientSessions: (5)
In this instance there is one user logged in but 5 UI sessions
