The system may have enough memory, but your 32 bit application is limited to slightly less than 4GB of virtual memory. Errno 12 corresponds to -ENOMEM. The process running out of its slightly-less-than-4GB of memory corresponds nicely with your system still having 12GB of free memory. This suggests you have run out of virtual memory space in the process. If your program needs more than 4GB of memory, eg. because you have a large data set, you need to use a 64 bit version of the program. This is not a kernel problem. - -- All rights reversed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTvi3EAAoJEM553pKExN6D1/QIAJ26mjn0UHz6MK1CPGywlvaZ JuE+2JvHrImHALnQ8jxQOutNLWp9IPzB/zByoyMkqUiJkrQ15aj60pyzZ9PvzuQo CX1ve3xMY/sf/617mRqRvbfCAbB3UArlXG4tU8OmzBdH4Qy/V6jFLY69hmFUqiXk hMIkG7NhuptYSwPmHV7vw4qTFDVUhh/p+etPYDeuAtDcFlScZ8CjdX2pzwR8TxPr M16UAOuhw2ONkZCO25XuM9AteKeLC85uV63gTgcm4h+W3Hqyeyebfsu7FmPkLq7v JavXFNL9gCMeVxgvjU6A7o+NjT8HNgkh/IPdE2LrqFysE6SeU77T61AcJEMJulM= =fmS4 -----END PGP SIGNATURE----- _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
