mayabatch 0xC0000409 error (1073740791)

Hello,

Out of no reason, we started to experience a completely random error on our render farm (various PC's various scenes that were previously rendered without a problem).   It shows as: error-code (0xC0000409) 

It also sometimes show as : 

  • libpng error: Read Error // Maya exited with status -1073740791
  • fatal flex scanner internal error--end of buffer missed.

It points to C:\WINDOWS\System32\ucrtbase.dll

 

here is a message from windows event viewer:

Attached is the report. Any ideas what might be the reason ? 

 

Thanks in advance

OK, Solution found- an error was caused by the file access problems. 

some details FYI:
I think the problem was a hardware/network issue, in particular Qnap Nas settings (one of these or both):

Asynchronous I/O - enabled in SMB settings,

Lock File (Oplocks) - enabled in shared folder settings.

 

After disabling both the problem disappeared.


hope it helps somebody one-day :).
