> Traffic server will crash in below steps:
> 1. Enable redirect and http cache, make sure that traffic server can cache redirect request & redirect response such as 302/307 response.
> 2. make a remap url in traffic server which will remap to a redirect url 'redirect_url_1' which points to 'www.google.com' ( note that 'www.google.com'  is also a redirect url which may point to 'www.google.com.sg')
> 3. make number_of_redirections=1 in records.config.
> 4. access the 'redirect_url_1'. At first time, after access it, traffic server will cache the redirect response such as 307.
> 5. try to access the  'redirect_url_1' again, this time traffic server will crash.
> The root cause is that in above case, traffic sever will check the cache in a loop definitely which will exhausted the stack space.
