Ignition 8.1.46 has been removed from our website and will be replaced with 8.1.47 soon. A change was made to fix issues with scripts being accidentally loaded multiple times during initialization, but in certain edge cases that fix can cause a deadlock. At this time we have decided to revert the changes and attempt another fix for the original issue. ---

Awww! Curious how closely the broken fix followed my advice... ---

lol, it was absolutely our attempt to fix your scripting bug that caused this. We've reverted it for 8.1.47. ---

Right, I know that. In my bug report, I provided a suggested solution. I obviously don't know if my suggestion was followed, or found to be flawed. I recommended serializing/synchronizing/locking on the project script manager. If that wasn't done, it would almost certainly deadlock in some cases. If it was done, and there is still a deadlock possibility, I'm **really** interested in how that happens. In my initial, detailed, report, I mentioned a "naïve" solution. That solution would _ **seem** _ to solve the problem for my equally naïve reproducer. ---

It wasn't your exact suggestion, but it was a reentrant lock held by the script manager around most operations in `ScriptModule`, so broadly similar and should've achieved the same end result. So far we've only had one customer report issues, so it seems to be a pretty marginal edge case, but it's bad enough and unknown enough that pulling it was the right move. ---

> [@paul-griffith](#): > > around most operations So, could be deadlock between a script init and some other operation? ---

A little birdie showed me the deadlock details. My suggested solution didn't account for the fact that python/jython aggressively locks around any use of the `import` keyword, using _ **its own lock** _. Sigh. Busted. 🤦‍♂️ Fortunately, using Jython's own lock for project script auto-loading is likely the right solution. Probably. Hopefully. 🤞
