REDHAT-BUG-767299
First published: Tue Dec 13 2011(Updated: )
It was reported that if a process that called glibc's svc_run() exceeded the limit of opened files for a longer period of time, that accept() in rendezvous_request()/svcudp_recv() would fail with the EMFILE error, which would lead to looping between poll(), accept(), and 'for' loops which would consume a lot of CPU time. This could lead to an unresponsive system that requires human intervention (service restart or system restart) to resolve.
