5520 WLC Switchover because of CP-DP Crash

[I0T]

Hi guys,

Do you have any idea what the CP-DP Crash means? To me, it looks like a hardware issue. We have a switchover about once a day. The mslog shows the following reason:

*spamApTask4: Jun 03 3:30:15.957: %RMGR-3-RED_WLC_SWITCHOVER: [SA]rmgr_sm.c:3368 WLC HA - Switchover Occurred, role changed from Standby to Active, Reason:CP-DP Crash, Peer HealthSt:0x10 (| Config changed |)
*spamApTask4: Jun 03 3:30:15.957: %LOG-3-Q_IND: [SA]rmgr_main.c:1636 Received Reload Notify payload from peer, Reason:CP-DP Crash, resetPeer=1[...It occurred 4 times.!]
*rmgrMain: Jun 03 3:30:15.950: %RMGR-3-RED_RELOAD_NOTIF_FROM_PEER: [SS]rmgr_main.c:1636 Received Reload Notify payload from peer, Reason:CP-DP Crash, resetPeer=1
