Hi Erik, Do you have 2GB of RAM on that server? if this is the case, you cannot have 8GB of RAM for the Diskcache:
-Dstorage.diskCache.bufferSize=8192 So this must be the reason. This is the formula: diskcache + heap < available ram So with 1,5GB of free RAM, try these settings: MAXHEAP=-Xmx700m and -Dstorage.diskCache.bufferSize=512 Best Regards, Luca Garulli Founder & CEO OrientDB <http://orientdb.com/> On 8 April 2016 at 10:14, Erik Pragt <erik.pr...@gmail.com> wrote: > Hi Luca, > > Thanks for your response. > > - I'm running on Digital Ocean, 2 core 2 gig version. > - Around 1500 mb. > - What kind of swap do you mean?
