I have fedora core2 installed with kernel: kernel-2.6.5-1.358
I must call system(....) about 300,000 times from a process that has 175MB allocated on a computer with only 256MB of RAM. But after about the 5,000th call, i get an out of memory error (errno: 12 Cannot allocate memory) when I call the system function.
Anyone heard of this? is there something that I should free? why is my 'Committed_AS' at 3TB?
