Re^2: Coro + LWP freezes (*trace)

Here what i get with perl-stacktrace:


root@elgato:/etc# perl-stacktrace 9366
[Thread debugging using libthread_db enabled]
0x00007f7ba19bd500 in __nanosleep_nocancel () at ../sysdeps/unix/sysca
+ll-template.S:82

        in ../sysdeps/unix/syscall-template.S
/tmp/3c5eHcBTdw.gdb:1761: Error in sourced command file:
Cannot access memory at address 0x1
[download]

What does that mean?

It might be that App::Stacktrace doesn't work with Coro. Or it might just be some other reason it doesn't work in your particular environment. The documentation for App::Stacktrace immediately mentions three options. If one were actually curious about what was going on, every one of those three options looks like something one would try. - tye	[reply]

This is debug by strace last calls: `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 ...>` [download] What does that mean? What to look for? Something with thread sor ...? There is a usleep command after my coro-using function to sleep, and as i see there's a work after thread execution and then there's a usleep, so it's the last in trace (nanosleep ...)	[reply] [d/l]
