compiler error message

[RonCagenello at UCBVAX.BERKELEY.EDU]

I've been Make-ing MetaFont on a 40/80GT and on a PI.  This is successful on the
40/80GT, but on the Personal Iris the following error is generated during
compilation of one of the programs: 
"ugen:internal:error in write, writing 272 bytes instead of 8192 bytes"
and "dksOdlsO: Out of space" comes up in the console window.  Can anyone tell me
what these messages mean, and what that implies for a work-around?

I appreciate your help,
