NSMTP 100% cpu

Hi all,

We are having serious problems with our smtp gateways servers.

Since we upgraded our Domino platform to 653 (Spanish language pack) we are having continous performance problems with NSMTP task.

The servers start all right, but after some time working, Nstmp task begins “eating” CPU, first to 50%,with the server really very slow, and after not a long time, to 100%. Finally the server hungs.

Once the server is restarted if works fine for some minutes or hours, but then nsmtp.exe begins the same, and it happens several times a day.

The server shows no crashes nor logs, and it is impossible to execute manuel nsd because the server hungs before it has finished.

Any ideas?

Thank you in advance.

Carlos
