Dude, CCR1009-8G-1S-1S+, database disk image is malformed

I’ve installed the Dude 6.34 on CCR1009-8G-1S-1S+.
Dude server crashes after 2 day.

 
 dude print
 enabled: yes
 data-directory: disk1/dude
 status: failure: database disk image is malformed: stopped

The dude server upgrade to version Dude 6.34.1 and after 2 day it crashes again with same message:

 
 dude print
 enabled: yes
 data-directory: disk1/dude1
 status: failure: database disk image is malformed: stopped

disk1 - the memory card.

Why is this happening and how to solve it?

I would try some other storage flash. Maybe that is what causes db corruption.

Thank’s. The problem has been in the memory card does. After replacing all works fine.
