Re: [issue1031] panic: hammer_mount: malloc limit exceeded
:Done. Panic still occurs, albeit after a longer time (about 30 minutes).
:This time --- marks a 2 second pause.
Ok, clearly I need to work on implementing limit_recs, which is a real
hack right now. That isn't my biggest concern at the moment so it may
be a week before I fix it.
My biggest concern right now is the machine lockup that was reported.
I thought I had fixed it but I can still reproduce it on my test box,
and since the box is locked up and I can't break into the debugger
finding the bug is going to be hard.
What I am doing to reproduce the lockup is (on a 2xCPU box), with
a HAMMER /usr/obj, is running three things in parallel:
window1: buildworld test
make buildworld -j 8
/tmp/fsx -S 123424 -c 100000 -l 4194304 -o 262144 -P /tmp/ test.fsx.dat
blogbench --iterations=100 -d /usr/obj/bench1
Needless to say, doing these three things in parallel stresses the hell
out of the machine. I don't even know if the bug is related to HAMMER
yet or not.
There is one more panic which occurs, related to direct-writes, but since
it panics and I get a core dump I expect to get it fixed fairly quickly.
The problem I really want to solve is the machine lock-up.
