Why is strace stuck at rt_sigsuspend, when I attach it to named process?
 

Hi!

I was trying to record the system calls a named process calls, when it is queried. I started named and attached strace to it by saying strace -p <pid> . I see that it is stuck at rt_sigsuspend but does not record any system calls. But I do get the response for my query. I was suspecting it could be because BIND9 is multithreaded. But this doesnt seem to work even in single processor system, with root privileges.

Could some one please help here?

-thanks.

Use the -f option to follow children. strace the master named process.

Thanks!!
 

Thanks a loooooot!! :-) It worked!
