It seems that the server is limited at ~32720 sockets... I have tried every known variable change to raise up this limit. But the server stay limited at 32720 opened socket, even if there is still 4Go of free memory and 80% of idle cpu...
Here's the configuration
~# 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) 63931 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 798621 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 2048 cpu time (seconds, -t) unlimited max user processes (-u) 63931 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited net.netfilter.nf_conntrack_max = 999999 net.ipv4.netfilter.ip_conntrack_max = 999999 net.nf_conntrack_max = 999999
Any thoughts ? (This question as been asked on stack-overflow with no luck so far)
