Sporadic error I found while testing with siege(1) #25

Open drforr opened 8 years ago

drforr commented 8 years ago

Running on a Ubuntu 14.04 64-bit VM, host Windows 7 machine running on Intel Core i5

$ perl6 -v This is Rakudo version 2016.03-45-gd0c675c built on MoarVM version 2016.03-46-g50c7f6a implementing Perl 6.c.

$ perl6 -Ilib bin/crustup eg/hello.p6sgi # in a tmux session $ siege -f siege.txt -r 1 -c 15 # where siege.txt consists of one line, 'http://localhost:5000/'

Sporadically generates this traceback, which I can't reliably reproduce. It also locks up at 'siege -c 16', probably due to threading limitations though I haven't yet played with the settings.

I can verify that the process dies when concurrency exceeds 15

Will try and reproduce myself when I get home from work

The recent changes in the Thread Pool Scheduler seem to have largely fixed this. It can quite happily take 32 concurrent clients now. With 64 I get one:

This is with:
