Hello, We are facing this problem too with 3 backend VMs and a NFS VM. Both servers are Google Cloud Compute Engine instances with plenty of CPU and RAM. We don't see any correlation with high CPU or RAM usage whenever this happens on any machine. When this happens, apache2 processes on a backend

Pulseaudio goes into an uninterruptible sleep upon start

2022-03-07 Thread Daniel Fishman
Hello, I have an up-to-date Debian stable machine where pulseaudio becomes stuck as soon as it is started (goes into an uninterruptible sleep). I couldn't understand what is the cause for this behavior - maybe somebody can provide an idea? Initially, pulse worked as expected - the ma

Hey folks, One of our users has a few processes that are refusing to die - according to /proc, they all have open file descriptors to his mailbox, and are all listed as being in the uninterruptible sleep mode. I assume that they are all stuck in I/O wait on that file for some reason - at any
