Linux tuning while running huge load using Jmeter

While running our jmeter load tests on Unix box with a target of 2500 User Load we got the exception “Non HTTP response code:,Non HTTP response message: Cannot assign requested address” in jmeter log We have set open files limit to 50000 and ran the test, but still we were getting the errors. $ ulimit -a core file size          (blocks, -c) 0 data seg size           (kbytes, -d) unlimited scheduling priority             (-e) 0 file size               (blocks, -f) unlimited pending signals                 (-i) 31182 max locked memory       (kbytes, -l) 64 max memory size         (kbytes, -m) unlimited open files                      (-n) 50000 pipe size            (512 bytes, -p) 8 POSIX message queues     (bytes, -q) 819200 real-time priority              (-r) 0 stack size              (kbytes, -s) 8192 cpu time               (seconds, -t) unlimited max user processes              (-u) 4096 virtual memory
