VERSIONS: versions 6.0 to 11.1
DESCRIPTION: This is a memory leak in the Program Global
Area (PGA) PGA is checked for Space leaks at logoff time and a leak was found.
There is no data corruption with this error.
ARGUMENTS: Arg [a] Logoff PGA size in bytes Arg [b]
"memory leak"
FUNCTIONALITY: MEMORY COMPONENT
IMPACT:
PROCESS FAILURE - but only during session delete so impact
is minimal

memory leaks.
Set the following in init.ora for example to disable space
leaks less than 4000 bytes
event = "10262 trace name context forever, level
4000"
and stop and restart the database. Repeated errors can be
diagnosed further by sending the alert.log and trace files to Oracle Support
Services.
