IRQ1 stops occuring due to IRQ7

Hi,
 
I am using two edge port interrupts in my design - IRQ7 and IRQ1. The issue I am facing is, when my system is running, my IRQ1 works fine for some time but later on, it stops occuring. The reason is possibly that, I get an IRQ1 interrupt while my IRQ7 is processing and I do not service it and hence, my IRQ1 never occurs again. Am I right in my understanding? How do I fix this issue?
 
Thanks very much.
