Yes, it fixes. After the patch curl-loader works with patched 2.6.19.7 and with patched 2.6.20.7 using simulteneous 3000 local connections smothly, and even better than with referred as a "good" 2.6.18.3. Besides that the tcp_mem status for my machine: kernel tcp_mem ------------------------------------------------------ 2.6.19.7 3072 4096 6144 2.6.19.7-patched 45696 60928 91392 2.6.20.7 3072 4096 6144 2.6.20.7-patched 45696 60928 91392 The patch was applied smothly just with line offsets. -- Sincerely, Robert Iakobashvili, coroberti %x40 gmail %x2e com ...................................................................
