I actually was just working on this right as you posted as we found it in 21.1 testing. CBRS has a small memory leak when saving the configuration file. Would you be so kind to send me your engineering.cgi so I can verify it is the same memory leak that I have fixed? The fix will be available in the next beta, 21.1 BETA-2.
Yes, unfortunately this memory leak was present in 20.3.1.2 as well. It actually goes all the way back to 16.X releases. This has been fixed in 21.1 BETA-2:
And mentioned in the release notes:
CPY-17920 - “calloc1 failed: out of heap” and “Internal error” due to memory leak with CBRS when changing config or exporting configuration
