This error can be found if administrators install more than one iSPI , for example iSPI for traffic , iSPI for QA or iSPI for IP Multicast and try to log in to NPS (Network Performance Server).


 This error can be found if the administrator log in to the NPS or run a report Java.lang.OutOfMemoryError: Java heap space


Installing more than one iSPI extension  might require more memory for bootstrap in order to run the report .


Edit the file /opt/OV/nonOV/cognos/bi/bin64/bootstrap_<os>.xml (eg bootstrap_linuxi38664.xml)

Increase the value of XX:MaxPermSize, eg:

<param condName="${java_vendor}" condValue="Sun">-XX:MaxPermSize=512m</param>

Important note:do not accidentally remove the 'm' after the size eg 512m
