Get Rid of the /lib/tls Directory
The new pthreads library /lib/tls installed by default on
recent Red Hat systems running kernel 2.4.x is defective. You
must remove it or rename it then reboot your system before
running Bacula otherwise after a week or so of running,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Bacula will either block for long periods or deadlock entirely.

The feedback that we have concerning 2.6 kernels is the same.
However, on 2.6 systems, you may want to use the loader
environment variable override rather than removing /lib/tls.
Please see Supported Operating Systems for more information on
this problem.

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.
The feedback that we have for 2.6 kernels is that the same
problem exists. However, on 2.6 kernels, we would probably
recommend using the environment variable override
(LD_ASSUME_KERNEL=2.4.19) rather than removing /lib/tls.
So, would you recommend that we use "export LD_ASSUME_KERNEL=2.4.19" or
"export LD_ASSUME_KERNEL=2.4.1"?
then you will get normal libpthread behaviour - so no nptl is used then
