tgz - "no space left on device" on "managed server"!

["Dampz, Joachim" <jo dampz dampz de>]

Hi,

I run in troubles with a preinstalled version 4.5.55 on two of my
customers managed servers.

It is not possible to view tgz-archives bigger than 256MB. 
I presume this is due to the fact that the /tmp directory has only this
size.
Im not able to change the size of this directory on this type of server.

Is it possible, with any parameter, to use another working direcory than
/tmp?
Or any other solution?

Best regards
Jo
