Hi We have implemented a picture server in Tomcat. The pictures are cached in a map. When the memory is nearly full, some entries are removed from map.
However, eventually the entries in the map become fewer and fewer even though the memory consumption stays high. In other words more and more memory are used outside the map. According to a heap dump done by jmap, there are many org.apache.tomcat.util.buf.ByteChunk instances referencing large byte[], which we suspect to be previously used pictures. We have tried both Tomcat 5.5.9 and Tomcat 6 under JBoss 4.2.0. Both showed the same behaviour. Are there any way to stop Tomcat from cached these large byte[] internally? The ByteChunks are referenced from IntermediateOutputstream, C2BConverter and OutputBuffer.
