Help HTC Desire HD - Text messaging Problem

[trickstyle48]

Earlier today, I was texting on my phone, and it was all fine. I later noticed that I wasn't receiving any texts at all, and I thought it was unusual... I had a check on my twitter, and because I use mobile notifications, I was a bit worried when I discovered that I should have received some texts/notifications, so I restarted my HTC and then all my messages from my friends and streaming notifications came in. So is there a problem with my phone now? Or is it just some annoying bug/glitch?
