Hello Gurus,

Environment: 10.1.0.4
OS : Solaris 9 (Sunfire V440)

Was casually checking process listing of oracle id and found a lot (about
70-80 processes) of <defunct> processes and most of these processes have
thier PPID as qmnc' s (queue monitor) or mmon's (mem mon) process id.  being
a test box I had killed qmnc and mmon and these processes disappeared.

I am closely monitoring the systems for these symptoms again and plan to
raise a SR with metablink. Have any one of you seen this before?

Best Regards

Sriram Kumar
