EventProcessor::spawn_thread doesn't check that there is enough event threads
and segfaults
-------------------------------------------------------------------------------------------
Key: TS-1035
URL: https://issues.apache.org/jira/browse/TS-1035
Project: Traffic Server
Issue Type: Bug
Components: Core
Affects Versions: 3.0.1
Reporter: Brian Geffon
The easiest way to see this bug is to use several hundred ports with accept
threads turned on. The bug exists because in I_EventProcessor.h there is a hard
coded limit of 512 event threads and there is no check in spawn_thread that you
haven't exceeded that limit so it will result in a segfault if you're creating
too many threads. From what I can tell the best solution is an assertion that
you haven't exceeded MAX_EVENT_THREADS.
Patch is included.
