SEGV?? Sure it is not running out of memory..try it in single user mode after doing a mount -a.. Check your enironment variables are set ok and export bash env | egrep -i "INF|TERM" >--- SIGSEGV (Segmentation fault) --- >+++ killed by SIGSEGV +++ >[ end excerpt from output_dbschema ] > >I'm not quite sure how to proceed, here.
