Hi Erik, It's hard to give you an answer here, this is the first report we have from a system that crashes without emitting any logs at all. In other cases, when we had an unexpected crash with few information, it was because of some OS related procedures (eg. process kill under heavy load), but also in that case we had a log stating that the server was killed.
Could you please share your logs? Maybe we will find some hints in the history Thanks Luigi 2016-04-08 2:18 GMT+02:00 Erik Pragt <erik.pr...@gmail.com>: > Btw, running OrientDB 2.1.9. > > > On Friday, April 8, 2016 at 10:05:33 AM UTC+10, Erik Pragt wrote: >> >> Hi all, >> >> As the question title suggests, our OrientDB database crashed today.
