Operation was not completed due to a database error

Every now and then (three times in total I believe) I get a database error when I login to the administrative web portal for OSSIM. When I login to the VM through Hyper-V Connect I get another error: OError: [Errno 28] No space left on device

And initially I just thought there was not enough hard drive space left, so I powered off the server, expanded the virtual hard drive, booted GParted live through the VM and added the space to the "/ partition". So the / partition was 100GB before and afterwards its 300GB.

Now comes the weird part, when I booted the VM after fixing the space issues, the machine booted with no errors, and I successfully logged in with no issues, I even could visit the administrative web portal that previously showed me the Operation was not completed due to a database error.

And then I tried to update the server and after that reboot the server started again with the errors of OError: [Errno 28] No space left on device. Even though when I run sudo df, I can clearly see that the hard drive has free space!

I'm currently only able to login to the VM through Hyper-V Connect and then Jailbreak, no access at all to administrative web portal.

What is the issue here? Have anyone else encountered this issue when the VM drive becomes full and you try to expand it?
