Resolution
In order to restore the service, stop / start the UVMS.
In order to avoid encountering this issue again, increase the memory settings of the UVMS to a higher value, like 1024MB / 2048MB or superior, depending on the number of nodes / users / services enabled on the UVMS.
You can do so via the uvms node settings -> advanced settings:
Maximum Allocated Heap Memory (Mbytes) -> 2048 ( or the desired value)
That should create a line on the values.xml like this:
2048
A restart of the UVMS is necessary to take this modification into account.
Fix Status: Released
Fix Version(s):
Component: Univiewer.Management.Server
Version: Dollar.Universe 6.7.01
