Leap second causing New Years RAC node crashes

5 December 2008

This discussion notes a potential problem with some Real Application Clusters sites, where the leap second adjustment has caused side effects.  Rajesh Rao notes a RAC node crash, possible related to the leap second adjustment:

“For clusters (10.2.0.2 as well as 10.2.0.3)  on Solaris 10, where we had retained css diagwait at the default value of 0.5, experienced crashes.  Nothing in the CRS logs. The OS logs have no messages except for Solaris booting up again.”

Also note this Solaris note on bug 6595936, which notes a time bug:

If you're dealing with a SunFire system, then add this to the etc/system file:

set tod_broken = 1
set
dosynctodr = 0
