-destination messages { file("/var/log/messages" suppress(30) owner(seife)> group(-1) perm(-1)); }; +destination messages { file("/var/log/messages" suppress(30) owner(-1) group(-1) perm(-1)); };

Is "seife" a user in /etc/passwd or perhaps a ldap (or other remote) user? When it is a not local one, this can cause a deadlock [e.g. getpwnam -> ldap-server -> syslog(3) on the log futex set in the glibc when the ldap- server runs on same machine]. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
