Not able to start the WAS v8.5.5 server after executing CFGJAZZSVR on iSeries

Check the server.xml to validate the heapsize. To view the server.xml file goto the following location:
/QIBM/UserData/WebSphere/AppServer/V8x/xx/profiles/<profilename>/config/cells/<cellname>/nodes/<nodename>/servers/<servername>/server.xml.
1. Verify the Initial heap size and Maximum heap sizes are valid. By default we set both values to 6144.
2. Verify the Generic JVM arguments are as follow:
-Xmn768m -Xgcpolicy:gencon -Xcompressedrefs
-Xgc:preferredHeapBase=0x200000000
