ERROR: xlog flush request 17/4D6C2720 is not satisfied

hi

My Postgres Server reports the next error message in log files.

“ERROR:  xlog flush request 17/4D6C2720 is not satisfied --- flushed only to 17/4CE03418”

Although Server up, Postgres does not function as expected - simple commands like “select * from <table>” or “drop database”  fails with this error

What is the cause ? how can I overcome?

Thanks,
