WAL makes memory full due to SAS token expiration

I am using CNPG 1.26 with Barman plugin 0.11.0 . I am taking backup on azure blob storage. I am using SAS token to connect with azure blob storage . But when SAS token expire and I forgot to update it . after that it looks like it stores wals inside pods memory which increases memory consumption which results it into pod not working. But After I update sas token it should release wal and make memory free. but it did not happen. It deletes the wal only after increasing the db cluster memory . Is there any other way to resolve this issue or release this memory.

@dosu, please help

No files or tests are named in the issue. Start by reproducing an expired Azure SAS token with CNPG 1.26 and Barman plugin 0.11.0, then inspect WAL retention and recovery after the token is updated. Done means queued WALs are released after credential recovery without requiring a memory increase.
