Shad Storhaug commented on LUCENENET-646:
-----------------------------------------
Version 3.x is no longer being actively supported, and anyone who was involved
with supporting that version is no longer involved in the project.
So, you basically have 3 options:
1. Upgrade to 4.8.0 beta. According to [Itamar's blog post from
2016|https://code972.com/blog/2016/07/98-lucene-net-4-8-is-in-beta-and-we-need-your-help],
it was then more stable then than 3.0.3 is. Since 2016, 4.8.0 has been
improved quite a bit. We have fixed all known crashes and cross-platform issues
as well as made several impactful performance improvements. Most importantly,
we are actively fixing any bugs that are reported.
2. Clone the repo and from the [3.0.3
branch|https://github.com/apache/lucenenet/tree/3.0.3], fix the issue you are
having, submit a PR back here and we will do what we can to get it released on
NuGet.
3. Fork the repo and from the [3.0.3
branch|https://github.com/apache/lucenenet/tree/3.0.3], fix the issue, and
deploy a private copy by your own means.
If you are using at least .NET Framework 4.5, I strongly urge you to consider
upgrading to 4.8.0-beta.

> This problem is critical because when it happens the application pool crashes
> and the entire website stops working with 503 error code.
> Errors are visible in Windows Event Log (Application), attached.
> When index files are deleted and index is rebuilt the problem goes away.
> I was not able to reproduce the problem by copying corrupted index files
> (also attached) to another server.
> By googling the error message it looks like it's coming from file
> CompoundFileReader.cs, method OpenInput.
> if (entry == null)
> throw new System.IO.IOException("No sub-file with id " + id + " found");
