what means: sockstat: sysctl(): No such process

[tequnix at frogmi.net]

hallo list

while running 

[ $(sockstat | grep -c saslauthd) -gt 90 ] && /usr/local/etc/rc.d/saslauthd restart

via cron (/etc/crontab, as root) (why i do this is of no importance
for this question), i get from time to time - about 3-4 times a day,
cronjob runs every 11 minutes - the message:

sockstat: sysctl(): No such process


i do not understand why i get this only sometimes, and what this
exactly means. 

i hope someone can help me and explain this behaviour 

thanks,
reinhard
