Hello Valtrec,

So I was able to spin up a new Clear Linux on a different Machine

http://gene.disi.unitn.it/test/show_host_detail.php?hostid=55927

Same deal, Clear Linux default install has issues, I'll let it run for a day more. If is producing invalid results, I'll try to apply the workaround on libz.so again to see if this will fix the issue.

I got it working, I have to replaced the libz.so file. (Hackish way)

My first valid results.

Wow, did we just discovered a bad bug? I'll see, if I can reproduce it again, using a different machine.

Ok, I installed an external gzip and replace the "clearlinux symlinked gzip"

$ gzip -V
gzip 1.9

And for a little testing, all default. Its clearly is different

Hello Valterc,

So, I chased down gzip. It seem ClearLinux is using ParallelGzip
If this is the default behavior of Clear Linux,
Is there a way for us to fix this?

======Clear Linux==========
$ gzip -V
pigz 2.4

$ which gzip
/usr/bin/gzip

$ ls -l /usr/bin/gzip
lrwxrwxrwx 1 root root 4 Oct 17 22:27 /usr/bin/gzip -> pigz

======End of Clear Linux=======

=====Ubuntu 18.04=======
$ gzip -V
gzip 1.6

=====End of Ubuntu======

P.S
*I turned off Boinc on this machine, since clearly there is an Issue/bug that needs to be solve
*Reinstalling gzip still installs pigz -https://clearlinux.org/software/bundle/gzip
