There were some recently fixed bugs related to the datatype being incorrectly guessed in some cases and then mishandled during rollup, (e.g. MONDRIAN-1469, MONDRIAN-1432). Definitely worth trying against the latest.

Subject: Re: [Mondrian] Conflicts between MDX Queries
Adding some more info, the issue we saw some months ago had to do with a query populating the segment cache with int values and the following query expecting to find double values for the same segments - but I think the error log was clear.
There's another issue filed by Cees van Kemenade (and recently solved by Curtis) that could be related - at least the symptoms look similar.
Kleyson, have you tried using the latest mondrian build ?

Unfortunately I couldn't find the query that makes the another queries
I have tried to eliminate one-by-one, but at the same time a query can
generate or not another to fail.
Looks be a relationship n-by-n between the queries where it is
impossible isolate the problem.
So I am using a workaround where is to run first the problematic queries.
If some modrian developer wish, i can share my dashboard and some data
to debug and try to figure out the problem.
As I said before, Pedro Vale from Webdetais told me that some time they
had the same problem.
If run A, B and C. C fail.
But If run C, A and B. No query fail.

After you asked me those question, I've realized that the error happens
only when the cache is empty.
So, in the first run of the 17 query dashboard I can see the errors, in
the 2nd time it run with no errors.
I will try figure out which query or queries are causing the problematic
one to fail.
