 In this case, there is no useful information for debugging errors and this is suitable for production mode.

+#### Known Restrictions and Issues
+1. In some cases running commands e.g. `npm build` can produce an Out Of Memory error.
+
+   When the error is encountered in Nodejs Selector UI or in terminal in web browser, check physical and virtual memory LVE limits. Also check process limits through `ulimit -v -m` command in Terminal UI or inside `/proc/<process_id>/limits` file. Increase the limits if necesarry.
+
+   On cPanel, increase the default process memory limit:
+   ```
+   whmapi1 set_tweaksetting key=maxmem value=8192
+   /usr/local/cpanel/scripts/restartsrv_cpsrvd
+   ```
+   In some cases, due to bugs in underlying Node.js frameworks (e.g. [Out of memory: wasm memory](https://github.com/webpack/webpack/issues/15584#issuecomment-1104603420)) it could be necessarily to increase `maxmem` upto 50 Gb (`51200`) or even to `unlimited`.
