Has anybody run into actual end user visible problems when using one of
weirdo PAGE_OFFSET configs?

In the past I saw that programs such as the Java Runtime (JRE) ran into
address space limitations due to a 2G/2G split on embedded systems.
Reverting to a 3G/1G split fixed the problems.

Right, that makes sense, given the tricks they likely play on the
virtual address space. Are the 2GB devices you maintain using a JRE,
or was this on other embedded hardware? How common is Java still in
this type of workload?

Sorry for the late reply, I was on vacation.

No, the devices with the JRE issues are from a different customer.
Since I work as a consultant lots of strange issues get thrown my way

I wouldn't say Java is super common but I still see it from time to time.
 
Thanks,
