Suddenly, the UVMS filesystem was full due to a huge .dat file that increased abnormously to several GB, like below:
-rw-r--r--. 1 univadm univgrp 2.9G Nov 21 08:19 c1060.dat
Over the week, the file could increase 1GB each week with no reason.
No particular operation was done at the UVMS level.
While reading the file with a text editor, it seem that the file contained the content of the table UNI_UV_USERSETTINGS, but this table only contained 3 rows, so the size is completely abnormal.
Release : 6.9 and superior
Component: UVMS using the Internal Derby Database
Unknown, most likely a Derby database bug.
The procedure would be:
1. Stop uvms
2. Backup the folder <uvms_folder>/data/data/uvmsdb
3. Go to the folder <uvms_folder>/app/bin and launch
./uniderby -q "truncate table UNI_UV_USERSETTINGS"
4. Start uvms
