tunable read rate program destination

When writing to a destination that requires syslog-ng to buffer messages, the memory footprint of syslog-ng grows endlessly, even when there is sufficient time
to flush the buffers.

I am including a read rate tunable perl program destination that I use to slow the destination down.

I am including a syslog-ng.conf file

I am including the output of valgrind.

I run syslog-ng, cat a /var/messages file (100,000 lines) to the input pipe.


valgrind now shows

definitely lost: 2,620,649 bytes in 4,439 blocks
