Here i pointed out in pink the split area of the vine.The red arrows point to something that looks like a nub wher maybe roots grow?But I think it may be insect eggs?

Oh yeah, I see it all the time, especially if I let my plants dry out and then water well. The stem splits from the pressure of fast water intake through the roots. But I've never seen it cause a problem with the plant's performance.
The nubbies will become roots if they touch the ground.

Thanks.. I've been watering once a day at 7am sunrise.
I never let it dry out but the weather is 100 degrees sometimes more.I hope its a normal thing with vines because I see it on 2 more vines now...
