As per my sense its a perm gen space issue
Do i need to increase size on bootstrap files ?
bootstrap_linuxi38664.xml
bootstrap_wlp_linuxi38664.xml
bootstrap_sg_linuxi38664.xml

Which files I need to update ?
or do I need to do anything else ?

We are using Red Hat Enterprise Linux Server release 6.6 (Santiago) and cognos 10.2.2

Thanks in advance.
