Hello Guys,<br><br>We are facing a strange situation on a customer.<br><br>During random periods, BigIron syslogs this kind of message:<br><br>May 20 15:24:13:I:System: CPU protection action2 deactivated at 000b7e00<br>May 20 15:23:48:I:System: CPU protection action2 activated at 000b7d00<br>
May 20 15:23:22:I:System: CPU protection action2 deactivated at 000b7c00<br>May 20 15:22:57:I:System: CPU protection action2 activated at 000b7b00<br>May 20 15:22:31:I:System: CPU protection action2 deactivated at 000b7a00<br>
May 20 15:22:05:I:System: CPU protection action2 activated at 000b7900<br>May 20 15:21:40:I:System: CPU protection action2 deactivated at 000b7800<br>May 20 15:21:14:I:System: CPU protection action2 activated at 000b7700<br>
<br>The box do have the "cpupro-action hardware-flooding enable" command enabled, with the default thresholds.<br><br>When the box goes this state we issue the "sh l2-cpu all" command, which shows:<br>
<br>SSH@BigIron#sh l2-cpu all<br><br>Condition Configuration:<br>01: 00000001 Atomic cpu dwm: 90, cwm: 60<br>02: 00000002 Atomic cam dwm: 90, cwm: 60<br>03: 00000003 Composite or(1,2)<br><br>System Condition Monitoring: *Exhausted*.<br>

<br>When this kind of thing happens, some servers/clients experinece connection losses (this is the box trying to go back to its "normal" state I suppose).<br><br>Unfortunately "show cam-partition detail" command does not show enough information for debbuging purposes.<br>
<br>Have anyone someone faced something similar ?
