Power off or reset the virtual machine. [root@amer network-scripts]# Message from syslogd@amer at Jan 27 12:46:38 ... kernel:NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [nova-api:102738] these Bugs of OSP 14 Nova were recorded because the system depends heavily on NSlookup to process it's function call, and I reported it to RH, launchpad.net,Bgzilla, and RDO. I have configured /etc/hosts several times and setup a named service (DNS), the service Nova overlooks the hosts and issues NSlookups to DNS, rabbitMQ fails and Nova because it depends on RabbitMQ in it's infrastructure code in python. | ||||||||||||
Steps To Reproduce | install OSP 14 and drop connectivity, it will produce some Bugs | ||||||||||||
Additional Information | it's on RHEL 7.6 platform and I don't really know if it is valid for Ubuntu, or any Debian variant, it shows that Kernel and Firmware is not compatible, so if you want to install OSP 14 , choose an updated version of firmware, and new equipment. | ||||||||||||

This is not an amule bug, this is because of high I/O load. You should tune permitted load with cgroups, maybe tune sysctl vm.dirty_bytes/vm.dirty_background_bytes. Search "linux bug 12309" for more information. |
