I could allocate more physical memory, but I can't seem to increase
the -Xmx option to 3800 I get
an error : "Could not reserve enough space for object heap", even
though I have more than 4Gb free.

I don't know much about java... but can you get any program to map
more than 4gb of memory? I know windows has hard limits on how much
memory you can map to one process and linux I think has some limit
too. Of course it can be configured but maybe it is just a system
configuration problem.
But still there should be a way to tell jetty to only have a certain
amount of threads/process/requests at a time, so you never risk the
problem of getting out of memory problems.
