Hello, I have one hobbit client that produces a core dump every 5 minutes when logfetch is run. It is running the same version of Hobbit client (4.2.0 with all the patches, which I believe has the same logfetch.c as the latest snapshot) as another machine and both have the same OS (including same version of glibc) and the same client-local.cfg configuration on the Hobbit server. However, only one of these machines core dumps. Here is the back trace: [root at myServer hobbit]# gdb /usr/libexec/hobbit/client/bin/logfetch core.2634 GNU gdb Red Hat Linux (6.1post-1.20040607.41rh) Copyright 2004 Free Software Foundation, Inc.
