 Description   

My Mongod just crashed this morning and I cannot restart or repair it.

It's a standalone setup. I have no idea how to recover the data. 

Error is :

// 
WiredTiger error (-31804) [1582531902:551403][1082:0x1177945c0], file:WiredTiger.wt, connection: the process must exit and restart: WT_PANIC: WiredTiger library panic

I've attached the log and the wiretiger turtle and wt files.

Can you please provide the mongod.log file covering the restart?

Thank you,

I've just tried , the server starts but it's crashing again as soon as you have multiple connection to the server with the following error:

// 
MongoDB::NetworkError: Unexpected end of stream

Hi philippe.baumgart@gmail.com,

I've attached a repair attempt of the files you provided as repair_attempt.tar.gz. Please extract these files, replace them in your $dbpath, and let us know if it resolves the issue—keep in mind that this repair effort may not be successful, and that diagnosing corruption issues requires significant information and effort.

Thank you,
Carl
