> Traffic Manager when autoconf fd > 32 will cause endless spins causing
> traffic_cop to kill server

> Key: TS-1469
> URL: https://issues.apache.org/jira/browse/TS-1469
> Project: Traffic Server
> Issue Type: Bug
> Components: Management
> Affects Versions: 3.3.0, 3.2.0, 3.0.5
> Reporter: Brian Geffon
> Assignee: Brian Geffon
> Fix For: 3.3.1

> WebIntrMain.cc uses a hard coded FD_SET Size of 32, so when the autoconf file
> descriptor is greater than 32 it will cause select to sleep forever since no
> timeout is specified. We had a few systems that would have continuous
> traffic_server restarts because they would (have a fd > 32) and would never
> accept the connection request for /synthetic.txt causing cop to kill mananger
> and server. But when Manager restarted is still got a high fd and it would
> happen again, while the whole time traffic_server is running just fine. This
> should be switched to FD_SETSIZE if available.
