2 identical setups, 2 different results, not enough par-blocks

Post by iio7 » 03 Apr 2020, 01:39

I have this very strange problem.

I have two different computers both setup with the same OS and both with the same version of NZBGet 21.0. Both computers have identical options setup (same configuration file).

From time to time I notice that a download has failed on the main computer with the error:

Code: Select all

Repair failed for foo/bar: not enough par-blocks, 1803 block(s) needed, but 0 block(s) available. Recovery files created by: par2j v1.2.1
When I notice that I switch on the other computer and download the exact same files from the exact same provider and it succeed. I have then tried to re-download again on the failed computer, and it keeps failing.

I have checked the physical memory for problems using memtest, but everything works as it should.

This only happens occasionally, but I wonder what possibly could be causing this error. Why is there a difference between the two computers (same NZB file, same provider on the same account).

Can this possibly be related to the difference in CPU? One is a Intel(R) Core(TM) i5-4570S CPU @ 2.90GHz, while the other, the one that fails, is a Intel(R) Celeron(R) CPU J1900 @ 1.99GHz.

I know that doesn't make any sense, but I am thinking about the evaluation that "1803 block(s) needed, but 0 block(s) available" on the Celeron box, why does it report that when it is clearly not the case?

Kind regards

Can you post two logs (one from failing and computer and another from working)? I mean the log from history item (not whole program log).

Thank you for replying.

I just had this very issue happen again for five different downloads. I will try to re-download on the two different boxes and then post the log ASAP.

So this is a snippet from the failed host. I have put the errors on top.

Code: Select all

On the successful host the same warning appears:

Code: Select all

warning	Mon Jun 08 2020 00:59:44	File archive.part21.rar has 87 bad block(s) of total 87 block(s)
But the repair is successful.

I have then tried clearing everything and re-download, but it is the same result.

repair completed but the data files still appear to be damaged.
This indicates a hardware issue. Disk, memory or CPU overheating.

That was my initial thought as well, however I have validated the box. The hardware is fine.

The strange thing is that it is only specific releases that it has problems with. Right after a failure I can download a big 70GB something and it repairs, extracts, etc. just fine.

That's why I am beginning to suspect if there is something else might be going on. Like different algorithms or something depending on something that the Celeron box doesn't support via a chip? Like when the hardware has a build in chip for decryption or decoding.

When this happens again try command "Post process again" from history, multiple times. It's interesting to see if it works after several attempts.

I will do that. I have only tried that once, in which case it has always failed again, but I will try multiple times to see what happens.

I have tried to re-process multiple times without any success.

Try to see these. I have copy pasted the Messages log from the box where it fails and from the box where it succeeds. This is the failed and this is the succeeded.

It is the exact same NZB file and an identical setup loading files from the same suppliers. I can't figure out what's going on. I tried downloading multiple times, same results.

There are many things which can go wrong when downloading from Usenet.

In the first post the error message was "repair completed but the data files still appear to be damaged." which is an indication of a hardware failure.

In the lat post the repair failure is caused by missed files. Which one of these issues you want to investigate? In any case when you post logs please post complete logs (of one nzb), not some part of the log you think is important. For example in the last log there are messages about missing files but I can't verify how they were downloaded because you removed the download part of the log.

In any case I strongly recommend you to read the log before posting here. In almost every case the log contains messages explaining why the download has failed.
