The problem occurs after logging on to the secondary portal for the second time the first time seems to work or after doing some actions .

Also the catalina.out is filled with the following error when the error occurs

Resolution

To resolve this please do the following on the secondary portal server. 

open the jforum-custom.conf file and edit the following line

database.connection.pool.max=10

change it to

database.connection.pool.max=25

Restart the secondary portal
