Hi,
We are facing the same kind of issues with apparently missing .si files in
our index folder. Getting Exceptions like these:
`org.apache.lucene.index.CorruptIndexException: Unexpected file read error
while reading index.
(resource=BufferedChecksumIndexInput(MMapIndexInput(path="C:\Windows\Temp\.SE71_.28\index\535321184\segments_1q")))

We've had this four times on three different installations now and we have
no clue what could be the cause for this. Currently using Lucene 7.4.0 on
Windows Server environments. Index is always on Systemdrive. Customers tell us,
that they did not delete files from the index on their own.
When I correctly read the thread here, then this issue was about fixing the
CheckIndex tool, but not about fixing the cause of the problem, right?
Also, the issue is still not solved, right? Any plans?
