Just for information, we run tomcat on HP-UX with no special tomcat limitation on max thread. We also use a NIS (aka Yellow pages) based JNDI authentification. We sun the sun provided NIS context for jndi. This tool is known by us to create something around 200+ temporary threads to get it's datas (yes awful!). We never hit a maximum Thread limit from the OS. Maybe it will be easier to ask the server admin to increase the max threads per process to something like 2000+ which is more reasonnable for a server imho.
Another solution could be to use green threads (JVM handled threads and task switching as opposed to OS handled threads and task switching) if they are available on your JVM....
