OOM in OrientDB Write Cache Flush Task

[Oleg Proudnikov]

Is this familiar to anyone? The server was not busy. There was a long running table scan query earlier from the Browser that would not respond to Interrupt - I simply reloaded the Browser page. I am not sure if the two are related. It has never happened before. Any suggestions would be very helpful.

Hi Oleg,

OOM stack trace does not show anything.

Real reason can be any where, do you have memory dump crated during oom ?

Hi Andrey,

Thank you for you quick reply. I do have a dump. Will have to put it somewhere for you to pull from. 

Regards,

Oleg
