You only have 150 threads, not 250. 150 is not a large number & is in fact lower than the default. At 50-60 requests per second, you must serve each request within 0.3s to avoid queuing requests (ie, using the acceptCount queue). You should avoid queueing requests. > At peak times, when all the threads are busy, new requests are rejected by > tomcat.
