non stabilized wood

[Predator]

I have a question concerning wood for knife handles. I have some stabilized wood for my knives that are burl type wood , thenI have some other wood that isn`t Burl wood and therefore isn`t stabilized. My question is the following.
What can be done to prevent it from cracking or separating from the handle after it is epoxied and pinned in place since it isn`t stabilized.I`m asking this , because a handle I put on a knife 10 years ago has started to lift away from the handle at the back of the tang. the knife is rarely used and when washed off , is dried.The wood I used was dry and I only finised it with linseed oil. The wood used was rosewood--slabs that I used.
I never had any trouble when I used Walnut.
I am curious since I will be using wood to hide the tang and do not want it to weaken and separate -- especially when I can not see it.
Thanks in advance
