Hi,
I have been developing an FCoE solution and have come across an interesting problem. When running mkfs.ext3 on a target connected via FCoE, my machine goes from 6GB of available RAM to 70MB in less than a minute. When checking the output of "free" from the bash prompt, I see between 1 and 2 million buffers allocated. None of the fcoe process show user space memory usage in "top". The same mkfs.ext3 utility does not cause this problem when using a target connected via an external SAS wide port. Is this a known issue or has anyone experienced it? Here is the connection "diagram": Host (my machine) <--FCoE--> N5K Switch <--FC--> FC Storage Here are details of my machine: * Montavista Linux 5.0 * 2.6.33 kernel (from kernel.org, with a few minor patches from us) * ixgbe 2.0.44-k2 (from the 2.6.33 kernel, our patch attached) * dcbd 0.9.21 * fcoe-utils 2.6.33 Please let me know what other information you may need. Thanks, Tristan
