*beast log files returns infinity for posterior and likelihood and a constant prior at aprox 22 million generations

What steps will reproduce the problem?
1. 20 species (is this too many?) 3 mit genes and 2 nuc genes unliked
models all with gtr estimate freq and gamma+i none are partitioned by
codon. Only one individuals per species. Trees are all unlinked because
BEauti v1.5.2.app will not create a working beast file if i link the mit
genes together. Relaxed clock:uncorrelated lognormal all estimate box
checked but one, this gene rate = 1 with sequences error model off. all
trees are randomly generated using speciestree:yule process pop size
continuous and root constant. All other priors and operators left default.
MCMC changed to 100 million.

What is the expected output? What do you see instead?

No infinity values.

What version of the product are you using? On what operating system?
Beuti v1.5.2 and beast 1.5.2 

Beuti v1.5.2 mac  

beast run on a Linux cluster consisting of 320 nodes (Dell PowerEdge M610).
Each node is equipped with two quad-core Intel Nehalem processors (2.8 GHz)
and 24 GB of memory.

This looks like an issue with the model/data being analysed rather than BEAST. 
My guess would be over-
parameterization or improper priors resulting in some parameters going to a 
limit. It may be a bug in the XML 
generated by BEAUti. More information is required to solve this -  the XML file 
for example and the final line of 
the log file to see which components have become -Inf. Look for other 
parameters approaching extreme values 
in the lead up to this.
