Hi,
 
I like to know what the numbers marked in red mean.I guess it is something 
like wait time in milliseconds. 
sgipcwWait()+880<-gipcWaitOsd()+396<-gipcInternalWait()+20104<-gipcWaitF()
 
I am also wondering about the moduls called.
E.g. gipcWaitF. My guess is that g somewhat stands for cluster and ipc might 
refer to network communication. These are waits related to the ocssd.
 
Regards
 
Lothar
