Memory leak problem

ROOT
1

Hi
I get the error message

Warning in TGraph2D::Build: Replacing existing 2D graph: Graph2D (Potential memory leak).

I don’t know how I can handle this problem. Who knows what I have to do?
cheers flori

you can find my C+±program which produces the error in the attachment…
gainuni.c (6.49 KB)

Hi,

call TH1::AddDirectory(kFALSE) somewhere before you create the TGraph2D. See ch. 8 in the users guide, ftp://root.cern.ch/root/doc/chapter8.pdf

Cheers, Axel.

It works, thanks for your response…

Sometimes it appears a second error:

sgslufread: Hard error on read, OS error = 32
sgslufread: Hard error on read, OS error = 32
sgslufread: Hard error on read, OS error = 32
sgslufread: Hard error on read, OS error = 32

probably it is a database error but I can’t find a solution for it…
The C+±program which produces the error is the same as before…

Hi,
google says it’s a DB problem, see e.g. tek-tips.com/viewthread.cfm? … 784&page=9
