[R] recurrent events

[avsha38]

Hello everyone,

I have a question about using "frailtypack" to run recurrent events data. 
I have a file with 1,580 events. The file structure fits the andersen gill
model.
When I run the file with all records, the R stops and shuts down.
Once I run only part of the file, about 400 events, R runs without a
problem.
Any idea why it happens?

In addition when I run a "Nested frailty model" with the below code, R stops
and shuts down as well:
cgd<-frailtyPenal(Surv(TStart, TStop,
Status)~cluster(Center)+subcluster(ID)+
Treatment,data=cgd.ag, n.knots=8,kappa1=50000) 

I would greatly appreciate it if anyone can help me out.
Thank you very much,
Avi
