Linked message upper limit

Is there a known upper limit on the number of
prims you can link together and have llMessageLinked
messages propagate to all of them?

36 seems to work just fine, but 49 has issues. It could
easily be that I'm doing something else wrong.

Thanks!

First of all, there is no hardcoded "limit" that I know of. Second, the tech limit is going to fluctuate, based on sim performance. Finally, milage will vary as based on where the messages are going - naturally, llMessageLinked(LINK_SET,...) is going to cause slower responsiveness overall than just singular messages to single sources.

So, as a general rule, it's probably safer to cram data if you can and use link messages wisely as opposed to getting as much spam in there as possible - llParseString2List and properly utilizing all three fields of a link mesage are the best ways to go about doing that.
