Has anyone got ideas or run across this intermittent export error?

Randomly getting this error in the export full. Metalink does not show anything related at our version so a tar created.

I think Expert Oracle: Database Arichitecture Chapter 3 (or 4 I don't have it in hand) will help you.

Hello List,

	I was little confused about the settings of pga_aggregate_target
	parameter. I was in a assumption that when we set this parameter to
a
	certain value, the usage of pga wont go beond this value. I have set

	pga as 3gb to one of my business critical database. Recently, I have
	found that max pga allocation was 4+ Gb. My boss askmed me, why the
	hell it takes more than what we have defined. I explained him saying
	that oracle might taken it from the OS to finish the necessary 
	request. His immediately counter question was, then what is the use
of
	setting pga_aggregate_target parameter? When oracle allocates and
	de-allocated the memory (pga) as per requirements.
	Is it expected behaviour that oracle takes sometime more that the 
	value defined for pga? If so, what is the benift of setting value
for
	pga?
	Thanks for your time.
