Floating point exception in parallel mode of fluent

i am doing simulation on 3 D wing which is having 6.5 million cells. my OS is windows 7 64 bit with 8 gb RAM and 8 cores (i am using 64 bit version of fluent). when i run the case by using 4 cores of the computer (i.e by starting fluent with command fluent 3d -t4) i get error as "primitive error at node 1, node 2 and node 3: floating point exception" after few iterations. As remedial measure i reduced my under relaxation factor and time step but the problem remained the same......
when i run the same case with single processor, the case is running okie under same settings. In order to save the computational time i have to exploit parallelism, i am trying to resolve this issue...... any body having any idea why this error is coming with parallel mode????
