Can you find the log file - or event in DW event viewer with additional information?

Thanks!

Sure thing Nicolai. This is shown in EventViewer and corresponds to the error we are seeing on the front end.

Hi Terri

We are looking at this one. We really would like a copy of your indexes when they are in this state - just a copy of the folder.

We have a code change that will ensure you do not see the error, but we need a copy of the index files so we can find the root cause.

Thanks, Nicolai

Hi Nicolai,

I'll be sure to grab them next time it happens.

Terri

You are a sweetheart!

Thanks, Nicolai

Hi Nicolai,

I can probably help you with that but from an older solution. 9.6.x

We constantly have this issue. Once maybe twice a day.

Adrian

Be happy to get an index where the error is!

Hi Nicolai,

Will send you a fresh one via WeTransfer.

I am archiving it now.

Thank you,
Adrian

I am sorry.

I was too slow. It got overriten by a coleague of mine.

Will send it over after the next crash.

Thank you,
Adrian
