Hi,

    We have a number of RAC environments running on IBM AIX servers at Oracle version 11.2.0.3. We have been experiencing some problems with one of these, and as part of our investigations we examined the 'cssd' daemon log file, an extract from which is as follows:

2014-01-20 15:47:25.313: [    CSSD][5671]clssnmCheckSplit: Node 2, irv73561, dead, last DHB (1390232818, 3261227246) after NHB (1390232796, 3261206061), but LATS - current (27150) > DTO (27000)

2014-01-20 16:02:37.366: [    CSSD][5671]clssnmCheckSplit: Node 2, irv73561, dead, last DHB (1390233729, 3262138999) after NHB (1390233707, 3262116979), but LATS - current (27371) > DTO (27000)

2014-01-20 16:40:46.305: [    CSSD][5671]clssnmCheckSplit: Node 2, irv73561, dead, last DHB (1390236018, 3264427826) after NHB (1390235996, 3264405579), but LATS - current (27443) > DTO (27000)

2014-01-20 17:07:15.027: [    CSSD][5671]clssnmCheckSplit: Node 2, irv73561, dead, last DHB (1390237607, 3266016486) after NHB (1390237586, 3265996212), but LATS - current (27301) > DTO (27000)

Howdy, Stranger!
