If you turn on USR1 and don't see any log messages than most likely it's a problem that isn't triggering one of the exceptions. You're turning it on right, and you should see a little log message saying it's on. If you've got a process that's "stuck" for some reason, try strace -p PID. Using strace you can see what system calls the process is calling and then see if it's in some loop or something. Another option--which is more advanced--is to attach to the process with gdb and then interrupt it and step through. I haven't used this yet, but check out Jamis Buck's blog and a few others for handy macros that can dump the Ruby callstack. > Are the 0.3.19pr items pretty much centered around the MIME type stuff or > should I try upgrading to that from .18pr? Yeah, it's MIME that was put into the 0.3.19 and just a few fastthread changes. -- Zed A.
