Sorry Jeremiah, I don't have a clue.......
got the same error (after the same 2 hours) after purging the
shared pool; there was no activity at all on the database, so
I thought about increasing the size of the shared pool (~10.5MB)
but had a need, and the option, of simply replacing the database
with a backup.
SQL> alter tablespace USR2 coalesce

ERROR at line 1:
ORA-04031: unable to allocate 4180 bytes of shared memory ("shared
pool","unknown object","sga heap","state objects")
