      Description

      Since we started running 1.5.0 qemu clients in SaaS we observe that devices becomes unresponsive approx each 3-5 days. Most likely the issue is in overflowing /var/volatile

      root@qemux86-64:~# df -h
      ...
      tmpfs           116M  114M  1.7M  99% /var/volatile
      root@qemux86-64:~# free -m
      total used free shared buff/cache available
      Mem: 231 31 3 186 196 6
      Swap: 0 0 0
       root@qemux86-64:~# du -sh /var/volatile/log/*
      ...
      1.9M	/var/volatile/log/auth.log
      27M	/var/volatile/log/kern.log
      27M	/var/volatile/log/messages
      27M	/var/volatile/log/syslog
      34M	/var/volatile/log/wtmp

      And just after cleaning the space the device become very responsive again.

      root@qemux86-64:~# > /var/volatile/log/kern.log
      root@qemux86-64:~# free -m
      total used free shared buff/cache available
      Mem: 231 31 15 160 184 30
      Swap: 0 0 0
