Hi, guys. I try to make async https requests with Coro + Coro::LWP + LWP::UserAgent my code looks like: 
my @requests;
while ( ... ) {
    push @requests, ...;

    if (scalar @requests % 3 == 0) {
        &doRequests(\@requests);
    }
}

sub doRequests {
    my $requests = shift;

    my @coro = map {  
        async {
             # here we get LWP::UserAgent object and to request
        }
    } @$requests;
}

The question is, my code should run all the time, but after running for a few hours or even hour it freezes. No CPU usage, no activity at all, like it's sleeping. This runs perl 5.16.1, latest Core, LWP. I'm wondering how to get know what is the reason for that freeze, how to know where it stopped? PS: i'm querying https host, if that matters. Addon: running strace gives this as last lines berofe freeze: 
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL, [], 0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1211417888, 0}, {1211354002, 168413065}) = ? ERESTART_RESTA
+RTBLOCK (To be restarted)
--- SIGWINCH (Window changed) @ 0 (0) ---
restart_syscall(<... resuming interrupted call ...>) = ? ERESTART_REST
+ARTBLOCK (To be restarted)
--- SIGWINCH (Window changed) @ 0 (0) ---
restart_syscall(<... resuming interrupted call ...>

What does this mean?
