Dear sap techs,
we made a kernelupgrade from 7.11 to 7.21 EXT of our PI system. As a perquisite of this upgrade, we had to update the SAPJVM from 5.1.047 to 5.1.084 (made it with JSPM). After the kernelupgrade the system starts (dev_server0 contains status (Running)), but no http-page is displayed (e.g. systeminformation or nwa). After changing SAPJVM version back to 5.1.047 the http pages are accessible again. Now the system runns with kernel 7.21 ext and SAPJVM 5.1.047, but oss 1716826 "Usage of the downward compatible kernel 721 (EXT)" states:
"Release 7.10 or 7.11: When using the SAPJVM 5.1, you have to install the latest patch collection, at least PC 58 (Build 5.1.074).".
