[Netarchivesuite-users] Corrupted ARC files

[Nicchiarelli Eleonora]

Hi Søren, 

the symptoms of corruption that we have had are the following: 

In the System State the BitArchiveMonitor has reported that for a file there was a failed upload. 
After inspecting the status of the file both on the crawler machine and on the repository to which we were uploading, we have found that already on the crawler machine the arc.gz file size was ~19 MB, and it was not possible to unzip it conventionally. 
Therefore we have concluded that the file had been corrupted right after being generated (possibly a case of bit rot on the crawler machine). 

Now we would like to "extend" the file to a valid arc.gz file so that it is possible to view its contents through wayback all the same (which is not possible at the moment). Is there a standard way to do this? 

Thanks in advance,

Eleonora
