[GRASS-user] multiple runs error

[AhmadKhaled]

Hi,

I am running 30 programs simultaneously on a super computer. After some time
some of them crash, giving the following error. 

Removing raster <tempPERMANENT>
WARNING: misc: couldn't be removed

LookupError: unknown encoding: string-escape

There is no pattern in the number of programs crashing, nor on the time they
crash. It seems that it is totally random. I though that there might be a
conflict between different mapsets, so I even used different locations for
different runs, but it didn't change anything. When I was running 4 programs
at the same time on my own machine I wasn't getting any error, so it is a
bit weird for me. I would appreciate if anyone can help.

Thanks in advance,
Ahmad
