Hi,
I am consistently running into out-of-memory issues in 8.1.4 running on
RHEL3 and 8.0.5 on RHEL4. The logs show entries like this:
AggContext: -2130714624 total in 271 blocks; 9688 free (269 chunks); -2130724312 used
TupleHashTable: 893902872 total in 119 blocks; 1088688 free (449 chunks); 892814184 used
which looks mighty suspicious to me. :-; I can provide a self-contained
test case if anyone wants to look at it.
