I can see that processes for different users executing trivial tasks are entering PRIV mode (AIX, DB2)
I found the below values from the system..

Its only using Roll Memory of 4MB, Whereas a lot more is available. Also, Private memory is showing 0 bytes, but the process is in Priv mode.

There is something wrong here with extended memory... but there is enough allocated > 590 MB... Is there something more I should check for ?
Default values of ext memory were increased.

Hello,
PRIV Mode: If a dialog work process has used up the roll area assigned to it and the extended memory, private memory is assigned to the work process. The work process goes into PRIV mode (private).
Following link can provide remedy to your problem.

Hi,
work process enters into the Priv mode when the Extended memory get used completely, look out the below(Maximum used), in your case the Em memory once get used completely, this is what you are getting the wp are in priv mode
Extended memory Dialog session kB 390,625
Nondialog sess. kB 390,625
Available kB 520,192
Used kB 245,760
Maximum used kB 520,192
this can be lot of reason, but to avoid this, you can increase the em/initial_size_MB value, and do check the other parameters like abap/heaplimit.
And we can restrict this priv mode by setting the rdisp/wppriv_max_no and rdisp/max_priv_time too.
Please check and update.
Thanks.
