In my dev box I have one mongodb instance that ran fine for months. Today, if I connect with Robo3t, and try to expand the functions node in the admin database, the engine will go down with the error

no cursor for uri: table

Other databases runs just fine, but the main problem is that, if I try to recover funcions list in admin db the entire engine will go down.

I've attached a log file (I have the full log file of 55MB, if you like to have it, please just tell me and I'll send you privately), if you need the entire content of admin db also tell me and I'll include them.
