Because there were not enough slots allocated. (I had this phrase

I don't know if you are talking about the maximum number of slots that
can be allocated by SGE on the node or about the number of slots
allocated for the job. Even if you have a maximum of 4 slots for a
node, SGE might decide to allocate only one from this node because of
it allocation policies (based on load, for example).
To find out if this is the case, in the batch script before running
lamboot add a line like:
cat $pe_hostfile
Then look in the .o file for the output. The second column specifies
the number of slots allowed on each node.
