Hi piscitella,

We haven’t heard back from you for some time, so I’m going to mark this ticket as resolved. If this is still an issue for you, please provide additional information and we will reopen the ticket.

Regards,
Thomas

piscitella, this could be related to SERVER-25974, which was fixed in 3.2.10. Please upgrade to 3.2.10 and report back; if the problem persists, please include:

  • The server full log from the last startup until the problem appears
  • The contents of the diagnostic.data directory

Thanks,
Ramón.
