Number of allowed concurrent connections reached, rejecting connection; client='AF_UNIX(anonymous)'

Добрый день!
Хочу посоветоваться прежде чем "решить" задачу. На сервере доступа, происходят такая штука творится:

Sep 16 18:20:48 vpn syslog-ng[2444]: Number of allowed concurrent connections reached, rejecting connection; client='AF_UNIX(anonymous)', local='AF_UNIX(/dv/log)', max='256'

....

Спам, жуть... Так вот вариант решения может быть увеличение max='256' до 1024 к примеру, или может быть.... ?

...или можно как-то исправить засирание "логов" pppd и pptpctrl ?
