How can Sys_Context ('UserEnv', 'Global_Context_Memory') return several million bytes for the current session while Select From V$Context returns no rows and also Select Sum (Length (Value)) From Global_Context returns 40 kB only ?
Oracle 19.26 with about 200 sessions.
Edit: After a restart, global context memory has returned from more than 4 MB to about 60 kB with about 700 sessions. So could this be a memory leak (Oracle bug) ?
