Hello:
Maybe somebody could give some clue about what is happening:
I have 6.5.0 running over Solaris 2.5.1 SPARC. I have a
database with 5 tables, 3 of them < 100 regs. and 2 ("usuarios" and
"passwd") with >10000. When querying for:
SELECT u.nombre_cuenta, per.nombre, pas.clave_cifrada,
pas.clave_plana, u.estado FROM usuarios u, perfiles per, passwd pas
WHERE (u.perfil=per.id_perfil) and (u.id_usr=pas.id_usr) and
(u.activa) \g
postmaster starts eating a lot of CPU and it doesn't finish to
process the query in +20 minutes.
Postmaster shows:
