Hi Team, I am experiencing an issue with my simulator where, at random phase of the flight the sim starts to freeze and un freeze every second or two. While trying to narrow down the cause, I found a couple of errors with respect to Simlink. Need your help to determine if Simlink is causing the issue. In the below log, the 0’s and 122’s synchronizes with sim freeze and unfreeze Error from Simlink Log: [2020-12-31 01:41:00] Status: 0; Last error: 183 [2020-12-31 01:41:01] Status: 0; Last error: 183 [2020-12-31 01:41:02] Status: 0; Last error: 183 [2020-12-31 01:41:03] Status: 0; Last error: 183 [2020-12-31 01:41:04] Status: 0; Last error: 183 **[2020-12-31 01:41:05] Status: 0; Last error: 183** **[2020-12-31 01:41:05] Status: 0; Last error: 183** **[2020-12-31 01:41:07] Status: -6; Last error: 122** **[2020-12-31 01:41:08] Status: -6; Last error: 122** **[2020-12-31 01:41:09] Status: -6; Last error: 0** **[2020-12-31 01:41:10] Status: -6; Last error: 0** [2020-12-31 01:41:11] Status: -6; Last error: 122 [2020-12-31 01:41:12] Status: -6; Last error: 122 [2020-12-31 01:41:13] Status: -6; Last error: 0 [2020-12-31 01:41:14] Status: -6; Last error: 122 [2020-12-31 01:41:15] Status: -6; Last error: 0 [2020-12-31 01:41:16] Status: -6; Last error: 0 [2020-12-31 01:41:17] Status: -6; Last error: 122 [2020-12-31 01:41:18] Status: -6; Last error: 0 [2020-12-31 01:41:19] Status: -6; Last error: 122 [2020-12-31 01:41:20] Status: -6; Last error: 122 [2020-12-31 01:41:21] Status: -6; Last error: 0 [2020-12-31 01:41:22] Status: -6; Last error: 122 [2020-12-31 01:41:23] Status: -6; Last error: 122 [2020-12-31 01:41:24] Status: -6; Last error: 0 [2020-12-31 01:41:25] Status: -6; Last error: 0 [2020-12-31 01:41:26] Status: -6; Last error: 122 [2020-12-31 01:41:27] Status: -6; Last error: 122 [2020-12-31 01:41:28] Status: -6; Last error: 0 [2020-12-31 01:41:29] Status: -6; Last error: 122 [2020-12-31 01:41:30] Status: -6; Last error: 122 [2020-12-31 01:41:31] Status: -6; Last error: 0 [2020-12-31 01:41:32] Status: -6; Last error: 122 [2020-12-31 01:41:33] Status: -6; Last error: 122 [2020-12-31 01:41:34] Status: -6; Last error: 0 [2020-12-31 01:41:35] Status: -6; Last error: 122 [2020-12-31 01:41:36] Status: -6; Last error: 122 [2020-12-31 01:41:37] Status: -6; Last error: 0 [2020-12-31 01:41:38] Status: -6; Last error: 122 [2020-12-31 01:41:39] Status: -6; Last error: 122 [2020-12-31 01:41:40] Status: -6; Last error: 0 [2020-12-31 01:41:41] Status: -6; Last error: 122 [2020-12-31 01:41:42] Status: -6; Last error: 122 At [2020-12-31 01:41:05] Below error was logged in Event Viewer (Time of issue occurrence in sim): Faulting application name: NavigraphSimlink.exe, version: 1.1.18.916, time stamp: 0x5f5f62f8 Faulting module name: ntdll.dll, version: 10.0.19041.662, time stamp: 0x27bfa5f0 Exception code: 0xc0000374 Fault offset: 0x00000000000ff0f9 Faulting process id: 0xcac Faulting application start time: 0x01d6deaa107e2d9a Faulting application path: D:\Program Files\Navigraph\Simlink\NavigraphSimlink.exe Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll Report Id: c1bd074d-d8d1-4e8f-96f1-10a8cbfe9ac3 Faulting package full name: Faulting package-relative application ID: Tests done: -Reinstalled P3D v4.5 and tried having only 1 addon at a time and did some flights - Issue occurred -Did Clean uninstall of v4.5 and fresh installed v5.1 and repeated 1 addon at a time - Issue occurred -Updated GPU driver, Rolled back, updated - Issue occurred -When the issue is happening, my PC performance status remained normal (~40 to 50% utilization) Throughout these tests, the only thing remained common was Simlink client. Observation: -Issue started only in the recent time, after Simlink was updated to the type which ‘Runs when PC starts’ (Single client compatibility for all simulators / Version that was released after FS2020 launch) -Issue occurrence is very random -Just before submitting this topic, I have uninstalled Simlink to see if the issue occurs again. Will keep you posted. I could not find any possible conflict/coincidence with other addons except this one. And the issue is so annoying. Simulator: Prepar3D 4.5 and 5.1 Overall Sim Settings: Never exceeded ‘Medium’ for any parameter. I prefer performance over visuals. PC Config: Intel i7-9700 RTX2080Super 32 GB RAM Please let me know if you need any other information. I am not a native English speaker, hence please forgive any grammatical errors that I have made. Thank you. Regards, Manoj Yadav ---

Hello Manoj! Welcome to the new forum. The issue looks to be the result of a failed installation of the Simlink plugin into the simulator. Future versions of Simlink will be able to notify the user about this, but until then, some manual action is needed. 1. Close the simulator if it is running 2. Open the Simlink application (from the system tray) and navigate to the “Plugin status” tab 3. Press “Plugin settings” 4. Find the entries for your simulators and press “Uninstall Simlink” for each 5. Press “Install Simlink” to reinstall the plugins. Please advise should this not solve the issue. Regards, Malte ---
