Attaching truss to the haning proccess shows continuous lines of:

ioctl(7,0xc0044d00 { IORW 0x4d('M'), 0, 4 },0xffffc1cc) = 0 (0x0)
ioctl(7,0xc0044d00 { IORW 0x4d('M'), 0, 4 },0xffffc1cc) = 0 (0x0)
ioctl(7,0xc0044d00 { IORW 0x4d('M'), 0, 4 },0xffffc1cc) = 0 (0x0)
ioctl(7,0xc0044d00 { IORW 0x4d('M'), 0, 4 },0xffffc1cc) = 0 (0x0)
ioctl(7,0xc0044d00 { IORW 0x4d('M'), 0, 4 },0xffffc1cc) = 0 (0x0)
