But my server keeps crashing when I run pg_restore: glibc detected *** double free or corruption (!prev): 0x0a00b1a0 Postgres: 8.1.4 Linux: 2.6.12-1.1381_FC3 glibc: 2.3.6-0.fc3.1 Server: Dell CPU: Xeon 2.80GHz Memory: 4 GB This is pretty repeatable. Any particular pg_dump file that causes the crash will cause it every time it is used, and it happens with a lot of my databases. What can I do to help diagnose this problem? Craig
