BodyContentImpls are pooled and reused since it makes JSP processing significantly faster. If the application is evil, and uses body tags with huge bodies (it seems to be the case here), then there could be a problem.
Large buffers may be discarded after usage, by setting the "org.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER" system property to "true". Unfortunately, performance will go down and GC activity will go up.
If you would like to limit the amount of resident memory that is used, you can disable pooling of buffer objects completely using the "org.apache.jasper.runtime.JspFactoryImpl.USE_POOL" system property set to "false". The performance will go down further due to object allocations and GC activity, but you may have a few CPU cycles to spare.
BTW, you can set system properties in the catalina.properties file (although you may set them on the command line too).
