REDHAT-BUG-767299: Low severity GNU glibc vulnerability
It was reported that if a process that called glibc's svcrun() exceeded the limit of opened files for a longer period of time, that accept() in rendezvousrequest()/svcudprecv() 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.
