[quote]Can you explain a bit more about the architecture here? Are you running a cluster?[/quote] 1.) I assume you are referring to the “ignition architecture” here? If so, we have a single server (Win2003) that is running both FactorySQL/Kepware/FactoryPMI (the FSQL/Kep/FPMI will be phased out once all projects have been “cutover” to Ignition), and Ignition. A separate Server is being used for the database (MS SQL2005 on Win2003).
2.) Although we have 2 sites both running in the above structure they are not “clustered” nor do they communicate with each other directly (both on different firewalled subnets).
[quote]Is there more than one designer altering the project at once?[/quote]Although we do often have two developers running the ignition or FPMI designers it is seldom that both would be working on the same “project” (this can be a pain if you both need to access the same screen for whatever reason - Saves/Updates/etc.). The majority of the time there is only one designer open & I’m fairly certain that this was the case in all instances of the “gateway not responding” errors.
[quote]If the problem is more prevalent when altering windows: can you isolate the problem to a certain window?[/quote] There doesn’t seem to be any “trigger window” to the problem. I have had it occur on numerous windows with the only common point being that there were changes that needed to be “saved” I.E. windows had been altered. Some of the windows are fairly “complex” in their design & do have a fair smattering of python script throughout but I’m not sure that you’d call this a “big” project or not (it’s about 1.6mb zipped)
I did have a problem with one of the windows becomming “corrupted” somehow (it would load but the components would not “redraw” unless the mouse was “clicked” over them) but was able to correct this by removing the affected window & reimporting from a previous backup of the same project. I could send you a backup of the project but I’m not sure it would do much good without the backend database. Let me know if you’d like a copy of the project (if it would help diagnose the problem further).
As a side note I notice that there is no “Reserialize windows” in ignition… Has this been removed as it was no longer required or not used?
