Can you try running common/thread/ThreadTester as root please?

Also both variants with -l 4 on the end to get us more logs.

See also this which has some potential workarounds/options from the looks of things:

[yurivict]

common/thread/ThreadTester succeeds when run as root with and without -l 4.

[peternewman]

common/thread/ThreadTester succeeds when run as root with and without -l 4.

Please can we see the output of common/thread/ThreadTester -l 4 then.

Can you also have a look at that linked thread and see if you can fix it by changing a permission externally to OLA?
