Just to confirm, still happens with -mm2?
Thanks,

No, it does not seem to. Evolution runs OK. ps, top, pmap all work
fine.
However, a couple of other things happened. Could be unrelated or only
loosely related.
Evolution launches spamd (spamassassin) to filter junk mail. spamd died
and I have this in dmesg to show for it:
VM: killing process spamd
spamd would have inherited the libhugetlbfs.so environment variables.
There are no other clues as to why it died though.
Also, immediately after launching evolution with libhugetlbfs, I got
that USB bug where the mouse starts creating keyboard input. I got some
of these in dmesg:
keyboard.c: can't emulate rawmode for keycode 240
That could be pure coincidence, although I had been using the system
almost all day before that, and it hadn't happened.

Interesting. Any chance spamd can be run manually with those env
variables, but with HUGETLB_VERBOSE=99 (and/or in gdb) to see what
happens to it?

Had you started evolution w/o libhugetlbs at all before that?
It does seem like that would be coincidence.
Thanks,
