Description

Hi Guys
I enabled ts_lua plugin and did experiment on my local computer all worked fine
when i moved to the big machine hosting traffic i noticed that the ATS crashes most often (each 5 minutes almost ).
i don't know the cause of it and can not confirm if its from the ts_lua stuff

plugins enabled are ts_lua, cacheurl, header_rewrite, collapsed_connection

anyhow here is the code i get in traffic.out
