Are you using pthreads ?

Nope.

Hmm I just found I had an FD leak - I am not sure if it's related.

Interestingly I had ~1046 FDs open and FD_SET wasn't working properly, eg...
fd_set fds;
int fd;

fd = 1046;
FD_ZERO(&fds);
FD_SET(fd, &fds);

Results in fds being empty :(

Does anyone know if that is expected behaviour? And whether this problem
could
cause the second one (eg tickle a bug).

Thanks.

In /sys/sys/select.h :
#ifndef FD_SETSIZE
#define FD_SETSIZE 1024U
#endif

so you should define FD_SETSIZE if you have fd which is larger than 1024.
