Re: [Dev] DAS going OOM frequently

Hi guys, So as Sumedha told me, the error that has come is a OOM perm gen error. And we suspect it's just because they've installed many features there in the IoT server, so lots of classes being loaded. So after increasing the perm gen size, Sumedha mentioned that the issue hasn't come yet.

Hi Sumedha, I checked the heapdump you provided, and the size of it is around 230MB. I presume this was not a OOM scenario. As per the Spark memory usage, when you use spark in the local mode, the processing will happen inside that JVM itself. So, we have to make sure that we allocate enough
