After executing command 'SIMPLE_LIBSDP=1 LD_PRELOAD=libsdp.so ./lt-ab -c 2000 -n 2000 -X 193.12.10.14:3129', there are some problems either: (1)sometimes server(running squid) occurred kernel panic. (2)client never connect server successfully. If using ttcp.aio to test, the error occurred on client is: [EMAIL PROTECTED] ~]# ./ttcp.aio -t 193.12.10.14 ttcp-t: buflen = 8192 nbuf = 2048 align = 16384/0 port = 5001 193.12.10.14 ttcp-t: socket ttcp-t: connect: Cannot allocate memory errno=12 [EMAIL PROTECTED] ~]#
