Hi,

We recently upgraded our virtuoso to latest stable version 7.2.1. We 
made a quad dump of the previous database and imported all the data to 
new virtuoso. When we started our process against the new database got 
an error on insert after about 1000 named graphs were added, with 
approximately 40 triples each:

SQL Error: XXXXX : COL..: Insert stopped because out of seg data here or 
elsewhere host 0 key RDF_QUAD slice 0

No error was logged to virtuoso.log file. Made an integrity check and 
that passed successfully, indicating that the database is intact. 
Removing the installed virtuoso and installing it again made it possible 
to insert data again for some time. Unfortunately I didn't keep track 
for how long or how many triples were inserted in that time. But it was 
not longer than about 5 hours. After that the error occurred again.
The database contains around 6 billion triples and the machine has 119 
GB of RAM.

What does this error indicate? Where can it occur, when the database was 
not corrupted?

Best regards,

Piret
