I had the following problem which caused ping and other applications to segfault. I believe the problem is in bind-utils. In /etc/hosts a line was accidentally repeated. 192.168.29.5 linfoo.eink.com linfoo ... 192.168.29.5 linfoo.eink.com linfoo Accessing all others hosts worked fine, but linfoo could not be looked up by domain name. "ping linfoo" and "resolveip linfoo" resulted in a segfault error. I recently upgraded my installation from Redhat-6.2 to Redhat-7.0
