Hi Team,

I am running database in version 11.1.0.6. I am facing  "Thread 1 cannot allocate new log, sequence #"  in the alert log frequently.

We have 10 redo log groups sized 500 MB each.

We have set log_archive_max_processes = 4, log_checkpoint_interval = 0, db_writer_processes = 2.

In addition, status is active for 3 redo log groups.
