If you have a recent Red Hat Linux system running the 2.4.x kernel and
you have the directory /lib/tls installed on your system (normally by
default), bacula will NOT run. This is the new pthreads library and it
is defective. You must remove this directory prior to running Bacula, or you
can simply change the name to /lib/tls-broken) then you must reboot
your machine (one of the few times Linux must be rebooted). If you are not
able to remove/rename /lib/tls, an alternative is to set the environment
variable "LD_ASSUME_KERNEL=2.4.19" prior to executing Bacula. For this
option, you do not need to reboot, and all programs other than Bacula will
continue to use /lib/tls.
This problem does not occur with 2.6 kernels.
