Hello all, since two weeks maybe a few days more I encounter a new problem with my local knime installation (3.7). whenever I start a bit more complex operation (table index + query; load a larger input file; run a larger GET request …) with knime the whole program freezes and can only be close using the task manager. I already reduced the RAM in the KNIME ini but the problem is still occuring. I’m using a i5 6300 2.4 GHz with 8 GB RAM and attributed 3 GB to KNIME. before the crash the PC gets quite noisy… Are more people facing this issue and maybe have an idea what might be the problem? best Andreas ---

Hi there! Reduced RAM? I would increase it… Also check this replay: > [@KNIME crashes with 6000x6000 table](https://forum.knime.com/t/knime-crashes-with-6000x6000-table/13143/4): > > If this is not related to problems we are seeing with Loops in the latest KNIME release 3.7 you could check out the various hints concerning KNIME performance. It could make sense to try and split the workflow up into several parts and see if that makes any difference. You could also try and monitor the Java Heap Space and see when that reaches a critical point. KNIME performance Br, Ivan ---

If you’re on Windows, perhaps see this thread and associated threads: [KNIME 3.7 Hangs in Windows 10](https://forum.knime.com/t/knime-3-7-hangs-in-windows-10/13026/4) If you’re not on Windows, could you give a bit more details as to what your workflow is doing? ---

Hi, > [@And\_Z](#): > > before the crash the PC gets quite noisy… To me, noisy means that the system is working with hard disk drive, so: 1- You may find it helpful to increase the amount of ram that KNIME can use: -Xmx6144m (=6 GB, considering your system resources. At least the half of your system RAM is recommended but I think you can increase it if you are not running any other application simultaneously) 2- You can increase the small table size (number of cells retained in memory): -Dorg.knime.container.cellsinmemory=10000000 You can read more [here](https://www.knime.com/blog/optimizing-knime-workflows-for-performance) and [here](https://forum.knime.com/t/knime-not-using-max-memory-java-why/5745).
