Views in Apex 4.1.1 is crashing the Apex engine

Question

Good Morning,
I have over 27 views in apex and made a column name change in the views and after I compile about 4 or 5 of them, the apex engine crashes. I was compiling the data views first, before moving on to report views.
When I upload the views and ran them in the as a script, it said all of the views were created.
When I went into object browser most of the views compiled. I recompiled the ones that were marked red. I compiled them in the code window, incase it threw an error, I can fix it there.
I had problems with views, before causing core dumps when I compiled them, but figured I had to compile the views in a certain order.
Any help on this is appreciated.
Using Oracle 11g
Apex 4.1.1
Thanks,
Mary

I know it's almost a cliche'd answer but... can you provide a bit more detail?
When I compile about 3 or 4 view in the code section of the view using the object browser it runs fine. It's when I go and compile another view in the code section, it will take longer to compile or freeze up and then throw an ORA-20876 error. I tell the dba whats going on and she checks and sees that the Apex engine has crashed and has to restart it.
I do not have access to SQL Plus or anything else. I will do this on the Oracle Hosted site to see if there is any problems.
The problem with the views before, was I was just compiling them and alot of my views use other views. So I just figured that I needed to compile the main data views, before the rest of the views, thinking that I needed to do compile them in order.
Update:
I uploaded 23 views that I had to change a field name in them to the Oracle Hosted site. They loaded and compiled fine. The views that didn't have any changes, there was a red mark next to them, so I recompiled them. There were no errors. Why do I have to recompile views that I didn't change?As you say, if there are interlocking dependencies between the objects in the view(s), on the initial run of the script they may well be invalidated. If you run the following:
create or replace view VW_FOO as
select sysdate tdate from dual;
create or replace view VW_BAR as
select (sysdate + 1) tdate
  from dual
union
select vf.tdate
  from vw_foo vf;
CREATE OR REPLACE VIEW VW_FOO
(TDATE, TDATE_2)
AS
select sysdate tdate, sysdate tdate_2 from dual;
View created.
View created.
View created.the View VW_BAR is invalidated, despite not being materially affected by the change to VW_FOO, on which it has a dependency - there are no errors displayed. Re-compiling VW_BAR seperately thereafter validates it.
