<p>Hi,</p>
<p><br>
</p>
<p>just for the record, after restarting mmsysmoncontrol on all nodes looks like the errors disappeared and no longer appear (and it has been running for several hours already). No need to change
<font size="2"><span style="font-size:10pt">usesharedlib</span></font>, which I have it enabled (1) for RHEL systems.</p>
<p><br>
</p>
<p>Thanks a lot for your help,</p>
<p>Marc <br>

<br>
This seems to be a bug in v5, open a support case.<br>
<br>
We had to check:<br>
<br>
mmdsh -N [AIXNode1,AIXNode2,AIXNode3] "grep usesharedlib /var/mmfs/mmsysmon/mmsysmonitor.conf"<br>
<br>
and to change:<br>
<br>
mmdsh -N [AIXNode1,AIXNode2,AIXNode3] "sed -i 's/usesharedlib = 1/usesharedlib = 0/g' /var/mmfs/mmsysmon/mmsysmonitor.conf"<br>
<br>
mmdsh -N [AIXNode1,AIXNode2,AIXNode3] "mmsysmoncontrol restart"<br>
<br>
Regards,<br>
Dieter<br>
