Im using ices2 under OpenBSD 4.1 to encode sound from the sound card.
The memory used by ices2 continuousely increases by about 2MB per hour?
Why is the memory usage increasing (or at least looking like it is)?
Is this usual and should this be happening?

I had a trawl back on the Forum and saw similar thing being reported when the CPU was fully utilised. This doensnt seem to be the case here as the CPU usage is very low.

here are the grotty details

After further investigation it seems it has something to do with the updating metadata.
If I stop the program that updates the metadata ices2 stops increasing memory usage. If I restart the metadata update ices2 keeps on increasing in size.
So the SIGUSR1 of ices2 must be causing this increase in memory usage.

ices-2.0.1
libogg-1.1.3
libshout-2.2.2
libvorbis-1.1.2
