Game lockup and Lua error in Atal Dazar M+ trash: "Script ran too long"

[brittyazel]

I was running an Atal Dazar M+ 18 key and during trash my game locked up for 2 seconds before returning to normal with this Lua error showing. This is the one and only time I've seen this error, so it's likely very transient, and I have no idea how to replicate it again.

This was when using DBM 10.2.13.

This unfortunately is just a blizzard problem. their script ran too long code is just really bad because the way they handle a script running too long, is by running one that takes even longer and locks game up and completely breaks addon in question.

As for actual issue here, its when the blizzard function PlaySoundFIle "takes too long" because it has trouble reading media from disk in 250ms or less, which can mean anything from slow disk read speed to antivirus or backup tasks or windows update was running in background at time it happened, slowing down file access. Something caused slow disk access in that moment. If it's an infrequent issue I'd just ignore it. if it's a frequent issue I'd investigate what's causing lower disk read performance and try to optimize that.
