[Help-glpk] 200Mb of Tables - xmalloc error

[Andrew B. Martin]

Hello,

 

I'm running a Windows XP 32bit with 1.95 Gb of RAM.

 

I'm am trying to build a model using .csv files, but am running out of memory (see xmalloc error below).

 

What is confusing me is that the combined size of the .csv files is no more than 200 Mb; when I hit Ctrl+Alt+Del and watch memory consumption in the 'performance' window CPU Usage does not crack 60% and PF Usage gets to 2.58 Gb when glpk stops building and the error pops up. It doesn't seem like a model of this size should exhaust my RAM, and the performance readings suggest it isn't. However, the error remains.

 

Does anyone have any suggestions as to why this might be happening?

 

Cheers,

Andrew
