Intermittent leakage of llRegionSay to channel 0?

I've somehow inherited a bunch of scripts that are sporadically spamming the entire sim with something that--as far as I can determine--is supposed to be in llRegionSay(). Now there's a jira item, about kinda related behavior when llRegionSay()ing to DEBUG_CHANNEL, but what I'm experiencing is not from DEBUG_CHANNEL, nor does it have the quaint "'Object say, foo' format" described in that jira. (And, of course, I've found no reliable way to reproduce it, so far.)

Before I make another jira item, has anybody else seen anything like this?

can you copy and paste one of the messages to show the format?

I've never actually gotten one of the accursed things myself, but from all reports, they look like:which to me looks the same as a normal llSay or llShout or llInstantMessage... except it blankets the entire sim, and only the sim, as would llRegionSay.

Hmmm. No haven't come across anything suspicious, but I live in a pretty sheltered sim, Anacortes Harbour. As the resident scripter, I'm the biggest danger :}

I take it the scripts you inherited are non-mod so you can't get a peak in them?

If it weren't for bad luck... As it happens, I have full perm for everything *except* the script that generates the offending text--so I can only surmise that it's doing an llRegionSay() inasmuch as everybody in the whole sim gets the messages when it misbehaves.

On the plus side, I have full perm on the scripts that are supposed to consume the text being sent, so I can "just" reverse-engineer the script I can't see and try to replace it. As it happens, an llWhisper() would suffice for what *should* be going on--which makes me deeply suspicious that some other Dark Magic is happening in that no-mod script.
