[11:38] <up_the_irons> I actually had to attach to init(1) with gdb and reap a zombie process.  Supposed to be a "this should never happen" scenario with init, but ...
[11:38] <up_the_irons> http://serverfault.com/questions/575162/remove-a-zombie-process-from-the-process-table
[11:39] <up_the_irons> It ended up working :)

[11:58] <brycec> Interesting. And here I thought a reboot was the only way to reap zombies.
[12:02] <brycec> (Trusty serverfault/stackoverflow - Initial question is "Yes I know the usual reasons *lists them off*" and someone responds with one of those reasons. Morons.)
[12:03] <up_the_irons> Yeah I never knew there was an alternative to reboot

[12:48] <up_the_irons> I think kvr18 just crashed
[12:54] <brycec> I'm inclined to agree :(
[12:55] <brycec> Description: No report from Monit for 182 seconds: the network, the host or Monit is down. Last report was 19 Jan 2017 15:45:53 -0500
[12:55] * brycec demands that up_the_irons fix it
[12:59] *** brycec[m] has joined #arpnetworks
[13:06] * brycec wonders why it's still down 20 minutes after it was acknowledged down
[13:13] <up_the_irons> brycec: i see everything up now; are you still having problems?
[13:14] <brycec> my vps hasn't phoned-home yet and isn't pinging. 1s while I check console
[13:14] <brycec> manual fsck >:(
[13:15] <brycec> (thanks for the prodding)
[13:15] <up_the_irons> :)
[13:20] <brycec> up_the_irons: thoughts/clues on what happened to kvr18?
[13:20] <brycec> (just curious)
[13:22] <up_the_irons> brycec: no idea; i was doing that zombie reaping.  worked at first, but then didn't subsequent times, and there was a VPS stuck in shutdown.  I've actually never seen it like that before, ever.  Maybe something was up with the host, b/c eventually the whole thing froze.
[13:22] <brycec> Huh, weird.
[13:22] * brycec ticks the "blame up_the_irons" reason tickbox
[13:22] * up_the_irons cries
[13:22] <mercutio> i'm not sure zombie reaping is helpful
[13:23] <up_the_irons> mercutio: VM wouldn't start until I reaped the zombie; then it started fine
[13:23] <mercutio> it used to be when things started zombieing that it was due to memory management etc bugs iirc
[13:23] <up_the_irons> I have no idea why all it's resources (tap, disk , etc...) were still held by the zombie
[13:23] <mercutio> hmm
[13:23] <mercutio> was that the same vps that got stuck?
[13:24] <up_the_irons> yup, got stuck 3 times
[13:24] <mercutio> weird.  t's still strange.  why that host, why that vm
[13:24] <up_the_irons> exactly
[13:24] <mercutio> it may be some weird race condition that hardly ever happens
[13:25] <mercutio> that broke something that made it break again

[20:55] <nathani> whats a zombie?
[21:00] <mercutio> when a process state says Z in top
[21:00] <mercutio> it's basically a stuck process
[21:00] <mike-burns> It's a child process that is not properly detached, right?
[21:00] <mercutio> https://en.wikipedia.org/wiki/Zombie_process
[21:00] <BryceBot> Zombie process :: On Unix and Unix-like computer operating systems, a zombie process or defunct process is a process that has completed execution (via the exit system call) but still has an entry in the process table: it is a process in the "Terminated state". This occurs for child processes, where the entry is still needed to allow the parent process to read its child's exit status: once the exit status is read via the wait system call...
[21:00] <mike-burns> Yeah, that.
