    Expedition becomes unresponsive and crashes every once in a while

    I’ve been using Expedition for long races and really love it. I finally found the time to post a question here about something that’s been bothering me for the past few years.

    After using Expedition continuously for a long time it becomes slow, unresponsive and finally crashes. Recent versions restarts automatically so that if you don't watch the screen at that moment you won't notice the issue. It restarts back, however after restart it loses all the tracks of competitors boats (using AIS) and loses active routings. 

    I have seen such issue on different boats which I raced as a navigator, with different computers, versions of Windows and versions of Expedition over the last 5 years.
    1. with CMap it crashes around every 24 hours
    2. with navionics it crashes more often, about every 3-4 hours

    Any ideas what can be the cause for that and if any workarounds are available? 
    I'm happy to provide more information, in my opinion I'm not doing anything fancy or special, just regular routing, boats tracking...

    Re: Expedition becomes unresponsive and crashes every once in a while

    Thats an interesting, and complex issue!

    FWIW, I have run Exp in complex setups (numerous serial connections, numerous UDP and TCP network connections, reading/writing via DLL from 3rd party (mine) apps etc) and run for days on end without any issues. I actually do a full system reboot every 2-3 days, maybe unnecessarily, to prevent any possible  system interruptions cause by any source (windows/expedition/3rd party apps/virtual serial port drivers etc) - since these usually occur at the least convenient time.

    So, only trying to think of anything out of the ordinary that you might be experienceing:

    - Windows version and level? i.e. Home/Pro etc - I always use Pro
    - User profile has Administrator permissions?
    - Odd folder read/write permissions in data dir? Witnessed in the past Windows config where permissions were not properly provisioned
    - Running Exp as Administrator?
    - Default installation locations?
    - Windows firewall/defender or any other 3rd party security apps? - I never use 3rd party
    - Assume latest version of Exp?
    - PC RAM? - for me these days minimum 32GB
    - SSD or HDD?
    - USB-serial or USB-ethernet adapters? If yes, standard drivers?
    - Tried an Exp system restore?
    - Are you migrating settings/files from/to? LIke Marks.xml, states, stripcharts, user config files, *.reg settings, etc etc?

    Re: Expedition becomes unresponsive and crashes every once in a while

    Thank you for the ideas and the questions, here are the details below:

    - was Windows 10 and Windows 11, Pro or higher. I was using Windows Remote Desktop to connect to PC from a deck tablet, not always, the problem exists without RDP
    - the user profile does have admin permissions, however Expedition is starting in "normal" mode without explicit elevation to admin privileges. I was thinking it would ask for admin permissions if they are needed
    - odd permissions on folders are unlikely, because it was on different PCs, with just standard installation, no fancy folders
    - yes, default installation locations
    - just windows defender
    - the latest version at the time of the race, as I mentioned in the previous post, I've seen that multiple times over past few years
    - RAM was usually 16Gb. I can try with 32GB, however I doubt how it would help with CMap - that version is 32 bit, it is not supposed to care about anything more than 4Gb. in your experience with 32Gb, how much does Expedition use?
    - always SSD
    - adapters activesense NGX-1 or NGW-1, standard drivers, yes
    - Expedition system restore? haven't tried, do you recommend trying it next time?
    - I did migrate some settings sometimes, not always, mostly marks if I was preparing the route at home before the race.

    - any considerations about GPU (graphical card)?
