## Which IIQ version are you inquiring about? 8.4p1 ## Share all details about your problem, including any error messages you may have received. We developed a simple plugin showing a view-only page listing all the responsibilities of a User (manager of non-personal identities, role ownerships and the like). I’ve deployed it on UAT and it worked without any problems. UAT has same setup as PROD (two UI-Servers, two task servers). However, on PROD, the plugin threw an “OOPs” error message. I’ve checked the backend calls, but they are working without problems. (I can call them form a rule and they return the correct output). After a while I realized if I uninstall the plugin and install it again, it works on that specific server - but still same behaviour on the other UI-Server. When I did unistall/install on second, the first would not work again. Now I’ve figured it is enough to just deactivate/activate the plugin to make it functional, and it seems it stays functional now. I’ve heard form other IIQ developer that this problem as popped up every now and then, but nobody seems to know why and what could be done to prevent it.. Does anyobody have some background info on possible reasons for this behaviour or the mechanism plugins are deployed form the DB to different IIQ servers? ---

As per the documentation, application server restart is recommended. Please try to restart and validate. ![image](https://global.discourse-cdn.com/sailpoint/original/3X/5/3/537b72706cc78218af5ce36b2d9819d87a0be3b9.png) [Developing Plugins](https://documentation.sailpoint.com/identityiq/help/plugins/developing_plugins.html) ---

I’ve not hot deployed this plugin, I rolled it out via SSB. So even then a restart is needed? ---

Hi Philipp How’s going 😉 ? When you deploy the plugin it ends up in DB. The server you deploy on will refresh and no restart is needed, by my experience tells me to restart ALL servers after plugin deployment. No matter how you deploy it. Regards Alek ---
