Lotus Daemon Terminates Prematurely

After starting the lotus daemon, it terminates after a few minutes. I’ve cleared the .lotus directory and this behavior continues. The common denominator is the following error which shows up in the console:

ERROR chainstore store/store[go]610 get message get failed

lotus version 0.2.8+git628a598c
Ubuntu 18.04.4

I understand that “Some errors will occur that do not prevent Lotus from working…”, but it would appear that this error is preventing the Daemon from continuing.

Any suggestions would be helpful.
