Crashing On Message

Well, I log on to Second Life. Everything runs smoothly, no crashing, not much lag in most areas. But within a second, to a minute after I send a message.. Second Life crashes. Now it has survived a message or two a couple times, but I can never make it through a conversation. And for some reason it seems like it crashes as the most important times in th game too. Like when I'm about to make a load of money, and ask the boss something. CRASH.

I re-installed the game, and even reset the cache to it and all. Just confused why it's doing this. What can I do?

Jeez, I can barely stay on for more than a minute. Trying to get a job done, but it's nearly impossible to do so. Not rushing you guys for an answer or anything, just respectfully stating that I hate crashing. Thanks for those who respond.

What version are you running?

Make sure you're running 1.18.2.

Also, try logging into a different sim than your current. Maybe it's the sim.
