the sleep() call, it was just a workaround.
SF Bug Tracker [ 3086852 ] 99% CPU loop in miniserver.c on a non ipv6
system.
Submitted by: Jin ( jin_eld ) - 2010-10-13 19:29:13 UTC
I cross compiled libupnp 1.6.7 for ARM9 using the --disable-ipv6
option, my system is an ipv4 only setup.
I do not know why this problem only appears when running the app in the
background (for instance using nohup &), but then it starts using 99%
CPU.
I traced the problem down to the select() call in miniserver.c in the
RunMiniServer() function. Select returns code 1, but errno is set to
"Socket operation on non-socket", I also see this when running my app
under strace.
I set all ...Sock6 variables to INVALID_SOCKET to make sure that they
do not get added to the FD_SET and the problem is gone.
