Getting:
"ORA-04031: unable to allocate 4256 bytes of shared memory ("shared pool",
"unknown object", "sga heap", "library cache")"
and
"ORA-00604: error occurred at recursive SQL level 1"
over and over in the alert log.

This is a "suddenly" event on a production database that had been
operational at 8.1.6 for a year, and is now at 8.1.7 for a month.  Running
SilverStream as a front-end, which has about 70 dedicated connections in
it's pool (SilverStream does MTS on its own). 

SilverStream users are unable to login.
I'm unable to login "sqlplus sys/manager", getting end-of-communication
channel.
I'm unable  to login "sqlplus internal", getting already logged in.
I'm able  to login "svrmgrl", but most commands end the session with a "not
connected".
  "startup" gives the expected already started, shutdown first.

My questions are (yeah, I know, clairvoiance):
  - Could anyone who experienced this share solution(s)?
  - Will a "shutdown immediate" just hang?
  - Will a "shutdown abort" cause harm? (Nothing but once-a-day full
export.)
  - What would you do?
