Leif Hedstrom commented on TS-4294:
-----------------------------------

Can you post some example URLs that was giving 502 errors ? Also, did you verify this to be an issue with 6.1.x? I.e. is this a regression from 5.3.x ?

> ATS version: 6.1.1
> Service Impacting Issue
> We came across an issue when placed ATS in the production environment. We have setup ATS with TPROXY as transparent caching for http traffic. The ATS box is connected on a single NIC to upstream router. The policy based routing is used to redirect traffic towards ATS box.
> We redirected some 4000 clients to ATS box, the clients were having established http connections when redirected to ATS. After shifting traffic in the error.logs we observed several 502 errors for some origins.
> The following tried but failed:
> Disabling/Re-enabling:
> proxy.config.http.keep_alive_enabled_out
> proxy.config.http.keep_alive_post_out
> Cold reboot
> Thanks
