I think this is a problem with glibc6 version (2.3.2.ds1-22sa) in =20
debian sarge and the NPTL. I confirm the situation on a Debian Sarge =20
machine. I got no errors with the following workaround:
export LD_ASSUME_KERNEL=3D2.4.15
/usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg
The /debian/FAQ from glibc6 contains the following section:
The application should continue to run for now, but when the warning message
is printed use of the NPTL threading library, and other new kernel-2.6
features, it's worth trying to set environment variable LD_ASSUME_KERNEL=3D2=
.4.1
(switch to LinuxThreads instead of NPTL).
Debian using glibc-2.3 Ubuntu 2.4, RHEL5 glib-2.5. Perhaps this could =20
be a reason? See the debian changelog of glibc6:
