Forum: Cfengine Help Subject: strange segfault Author: neilhwatson Link to topic: https://cfengine.com/forum/read.php?3,20855,20855#msg-20855
Yesterday morning cf started segfaulting on just one host. This not a new install so my assumption is that something on the host other than Cf has changed to cause this. The gdb output is odd. Can anyone here make sense of it? ippdd01:/var/cfengine/outputs # /usr/bin/gdb /var/cfengine/bin/cf-promises GNU gdb 6.6 Copyright (C) 2006 Free Software Foundation, Inc.
