標題: Postgresql9.1.6在大量進行insert和空間查詢時內(nèi)存溢出的問題
目前是這樣的，要做一個網(wǎng)絡(luò)分析。所以會有大量的空間查詢和insert操作進行。
發(fā)現(xiàn)在大量操作時，會導致系統(tǒng)內(nèi)存溢出，進而數(shù)據(jù)庫的progress就crash了。無法再連。
下面是截取的日志，這個上面是大量的SPI TupTable這樣的語句，非常多。

還請大家不吝賜教啊。

報一下具體啊
操作系統(tǒng)版本，內(nèi)存大小，cpu核數(shù)，數(shù)據(jù)量大小，數(shù)據(jù)庫shared_buffers, work_mem 等等

回復 1# letheanwater

肯定你用了C語言寫的擴展，而那個擴展里面有bug，從異�？磻�(yīng)該是訪問非法內(nèi)存位置。
