Hi! We use postgresql-6.5.2, on i386-linux (Rh.6.1), from 4-5 Xterminal, the apllications, and postgres runs on the same machine. there are approximately 30-40 inserts|updates /min. The performance is pertty well... but there are many backend crash (~10/day) ;( And after a crash some dust remains: uninitialized pages in tables, wrong indices..., and this dust generate a crash again. (if i not run a vacuum) I tried, to dump-initdb-restart, but it doesn't help. We use many user-defined functions (some C, but mostly plpgsql) this under test circumstances (on another machine) works fine, and i trust in postgres stability. So: Meet somebody with similar things? How can i find the reasons posteriorly? Can be the cause of the random backend smash broken hardware? Other advices? Thanks...
