Hi, We are seeing a very strange thing with the port we are using 33000. Our daemon hvmmgrd uses port 33000 but when hvmmgrd dies, xl/qemu-dm/tapdisk2 processes grab that port and we are not able to restart our daemon. Why does qemu-dm/xl/tapdisk2 go after our port? We have tried changing to different port numbers but the qemu-dm/xl/tapdisk2 processes are going after that port only. It almost feels like kernel is giving back last freed port. But why? lc-4:/tmp # netstat -tulp --numeric-port Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:16111 *:* LISTEN 31651/ssc_podd tcp 0 0 *:111 *:* LISTEN 13173/rpcbind tcp 0 0 *:54001 *:* LISTEN 31601/cardmgr tcp 0 0 *:22 *:* LISTEN 13848/sshd tcp 0 0 *:7800 *:* LISTEN 21380/dlm_hostd tcp 0 0 *:680 *:* LISTEN 1351/bamc tcp 0 0 *:111 *:* LISTEN 13173/rpcbind tcp 0 0 *:22 *:* LISTEN 13848/sshd tcp 0 0 *:11008 *:* LISTEN 21354/save_techd tcp 0 0 *:33000 *:* LISTEN 26475/hvmmgrd udp 0 0 *:111 *:* 13173/rpcbind udp 0 0 127.0.0.2:123 *:* 14957/ntpd udp 0 0 localhost:123 *:* 14957/ntpd udp 0 0 *:123 *:* 14957/ntpd udp 0 0 *:625 *:* 13173/rpcbind udp 0 0 *:679 *:* 1351/bamc udp 0 0 *:111 *:* 13173/rpcbind udp 0 0 localhost:123 *:* 14957/ntpd udp 0 0 fe80::ff:fe01:308%6:123 *:* 14957/ntpd
