Here is what TAC gave me while ago for IA debugs, maybe give it a go and see if anything useful is there.

(•)•) Identity awareness debugs
# cd $FWDIR/log
# rm pdpd.elg.*
# echo "=debug_start=" >> $FWDIR/log/pdpd.elg
(•) To turn pdp debug on:
# adlog a d on
# pdp debug on
# pep debug on
# pdp debug set all all
(•) Replicate the issue
(•) To turn them off:
# adlog a d off
# pdp debug unset all all
# pdp debug off
# pep debug off
# pdp d reset
# pep d unset all all
Collect debug:
$FWDIR/log/pdpd.elg
# tar zcvf pdpd_debugs.tgz pdpd.elg*
# tar zcvf pepd_debugs.tgz pepd.elg*
Best,
Andy
