--------------------------------
Summary: Traffic Manager when autoconf fd > 32 will cause endless
spins causing traffic_cop to kill server -- Backport 3.0.x
Key: TS-1483
URL: https://issues.apache.org/jira/browse/TS-1483
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.
