Hi, I try to delete a larger graph (300M triples) on my VOS7 store (07.00.3203-pthreads for Linux, Database version 3126) but VOS crashes on a memory problem. I down scaled memory assignment in virtuoso.ini to 12GB (the box has 16 GB, previously 14 GB was assigned) in virtuoso.ini ; 12 GB NumberOfBuffers = 1020000 MaxDirtyBuffers = 750000
But it keeps crashing (see error below). What is my problem here? Does anyone have a suggestion on how to proceed?
