I work on a fairly large Ruby application that runs as a daemon,

The foreman's apparently trying to lock the Global Vm Lock to do a
malloc().
Several questions:
1) How to tell which thread owns the global_vm_lock? In gdb, printing
th->blocking_region_buffer for the main thread returns a pointer to
something, while another thread returns a zero value for
blocking_region_buffer. This suggests that the other thread owns the
global_vm_lock. On the other hand, if I dump the actual global_vm_lock,
the __data.__owner is 5488, the thread id for the main thread. I'm
thinking that this thread is trying to lock the GVL when it already has
it, but I'm not sure.
2) in frame 8, the rb_str_buf_new should be requesting 129 bytes, yet
the size parameter in frame 7 is more than 160 Megabytes! This huge
allocation appears to be what triggers garbage collection with gvl. How
this happens is a complete mystery.
3) within gdb, is it possible to figure out what the content of the
backtrace would be if it didn't hang? I know that ruby's backtrace stack
is somewhat complex - any pointers to simple-ish ways to find out where
the ruby interpreter is?
Thanks,
Bill Paulson
