syslog stops to deliver to console

Hi

I have ppc arch and sysklogd-1.5 working on it.
The syslogd has config file which orders to redirect output to console (/dev/console) and IP of other Linux machine.

I have application with 3 threads doing syslog every 50msec. After less that minute the console stops to show messages, but the other Linux machine still gets them.

Is it known problem?

Thanks for help.
