Subject Segfault with 4.1.1 using url_regex and proxy.config.remap.num_remap_threads > 1
Date Fri, 22 Nov 2013 01:33:56 GMT
I just upgraded a dev server to 4.1.1. I'm looking to do Lua-based remaps,
so I figured turning up proxy.config.remap.num_remap_threads would be good.
I was playing around with cache.config and noticed that if I have
proxy.config.remap.num_remap_threads set 8 and I try to use a url_regex in
cache.config, I get a segfault with the below stacktrace. I don't get a
segfault with proxy.config.remap.num_remap_threads=0 nor
proxy.config.remap.num_remap_threads=1 (though I thought I did see it once,
but can't replicate now). I also have no issues with
proxy.config.remap.num_remap_threads=8 but using dest_domain instead of
url_regex. ATS newbie, so expect something dumb on my part.

Incidentally, any guidance on what the appropriate value for
proxy.config.remap.num_remap_threads should be for a remap-heavy system?
Equal to # of cores?
