This seems to be a bug in v5, open a support case.

We had to check:

mmdsh -N [AIXNode1,AIXNode2,AIXNode3] "grep usesharedlib /var/mmfs/mmsysmon/mmsysmonitor.conf"

and to change:

mmdsh -N [AIXNode1,AIXNode2,AIXNode3] "sed -i 's/usesharedlib = 1/usesharedlib = 0/g' /var/mmfs/mmsysmon/mmsysmonitor.conf"

mmdsh -N [AIXNode1,AIXNode2,AIXNode3] "mmsysmoncontrol restart"
