https://devzone.nordicsemi.com/f/nordic-q-a/78508/civetweb-crashes-on-nrf91-when-larger-website-is-requestedHello, I am currently working on an IIoT product using Zephyr and NRF SDK v1.5.1-2-g76c027893 on the NRF9160 and a WFM200 wifi chip. For this project we are using Civetweb as a webserver serving a website of about 600KB in size.

The actual crash might be just a result of some memory corruption caused by a different module, but it&#39;s hard to tell&nbsp;without a&nbsp;debugger.</div> <div></div> <p></p> <p>We&#39;ll need some more information about your setup since the actual crash seems to be related to the WiFi interface you&#39;re using. What driver are you using?</p> <p>We don&#39;t have any native WiFi drivers in the tree, they&#39;re all offloaded for now, and offloaded sockets don&#39;t use net_pkt.</p> <p></p> <p>Best regards,</p> <p>Heidi</p><div style="clear:both;"></div>
