It's a fact that 32-bit Pan runs out of *process* address space at
around 2GB. 64-bit Pan doesn't technically have that problem, but
effectively it does, although it does for all practical intents.
Well, the 32-bit part isn't quite accurate, or at least it's accurate
for only a subset of 32-bit.
It's completely accurate for the set of people who use pre-built Debian
and Ubuntu kernels.
You mean they don't have a 32-bit "enterprise kernel" or perhaps a
"enterprise/database kernel" or similar, with the 4G/4G userspace/
kernelspace option enabled? Given that database-server targets have
been, by my reading, the primary use of such a config, I'd have expected
they'd have at least one such kernel option available.
But perhaps it is accepted that such "advanced server usage" requires a
reasonably good sysadmin, where "reasonably good sysadmin" is defined in
part as having (or at minimum, knowing where/how to get) the knowledge to
properly reconfigure and rebuild the kernel with that option enabled, if
they need it.
