Eviews crashes when restructuring page

[tvonbrasch]

Hi

I have a large panel data set. When I try to balance the workpage Eviews stops working (see attachment).
pagecopy(page=w1less2, smpl="@all if w1<3" )
pagestruct(balance=sem) fnr @date(dateid)

But it does not happen all the time. Sometimes these commands works and sometimes Eviews stops working.


I'm wondering if it has something to do with the size of the workfile? It holds 26 mill observations. Can Eviews become unstable when using such a large dataset?

Is there a code I can use so that the program stops or Eviews shows an error message instead of Eviews crashing?

Hard to say, we'd need to see it. But with 26m observations, I presume the workfile is too large to email?

Hi

Yes, it is too large to email and the data is confidential....

Is there something I can do to check what is causing the program to stop?

I noticed that it crashed when running the sequence

smpl if vh>0 and vh(-1)>0
genr aux= v/@sumsby(v,@date)*(1/h1)
smpl @all
genr i_p= (@sumsby(aux, @date))^(-1)
genr i_f = @sqrt(i_p*i_l)

Could it be a problem if h1 is approx zero for a number of observations?

Possibly. There isn't really anything you can do other than artificially stopping the program to try an narrow down which line causes the crashing.

Hi Gareth,

There is nothing wrong with the code. For some strange reason, when I log on to my work from home the program executes without a problem. But when i run it from work it crashes. Interestingly, as you can see below, the amount of RAM used when loading the workfile is almost 20 GB. And when I execute the program it stops. Can this be due to the max amount of RAM on the server being 20 GB? Have you encountered such a problem before?

Any help and/or suggestions is greatly appreciated. Is there something I can tell the IT department to check?

Sincerely

Looks like you're just running out of memory then. I can't recall seeing an operation that uses 20GB before...

Hi

ok. i think the job is only at about 12 GB, but when other people at work are using memory too, it crashes.

Thanks again.
