When I doing some benchmark for outbound proxy, and has http_cache
enabled, well, first of all, the performance are pretty low, I guess I
didn’t do it right with the cache enabled, 2nd when I use wrk to have
512 connection with 40 thread to go through proxy with http, it cause a
core dump, here’s the trace
And when I disable the http.cache, the performance has went up a lot,
and no more coredump at all.

is this repeatable?
which version of ATS?
at least mention the software version should be common-sense
had one such crash after upgrade to 7.0.0 and was not able to reproduce
it, even not with a "ab -k -n 10000000 -c 500" benchmark
