Logs keep stoping

Hi,

I have this problem, that my qmail logs system often stop logging.
It happens a lot of times during the day.

If i run svstat /service/*/log everything seems ok, but the system is
not logging any of the services and "current" file disappears.

/service/qmail-popup/log: up (pid 8958) 82 seconds
/service/qmail-popups/log: up (pid 9373) 1 seconds
/service/qmail-send/log: up (pid 8961) 82 seconds
/service/qmail-smtpd/log: up (pid 8962) 82 seconds

What could be causing this ?

Following my signature is /var/qmail/supervise/qmail-send/log/run
(the others are preety much the same).

Any help would be appreciated.

Warm Regards,
Mário Gamito
