I just rebooted and ran a similar load of network+disk load that made the machine give "swapper allocation failure" messages before, and I couldn't reproduce it with 2.6.35: 2.6.35-19-generic #25~lucid1-Ubuntu SMP Wed Aug 25 03:50:05 UTC 2010 x86_64 GNU/Linux Doing "sync" in the middle made sync take more than 5+ minutes to complete (2 hung-task messages in dmesg), but at least nothing ran out of memory. Considering the amount of people running 2.6.32 and who will be running it in the future, it still worries me that this is present in 2.6.32 (and earlier kernels as well). -- Mikael Abrahamsson email: swmike@swm.pp.se -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
