I use xfire 1.6.2 with tomcat 5 and java 1.6. If I run 400-500 threads with
strongly load my server, after 10-15 minutes I get some exception:
21:51:36,145 ERROR XFireServletController:134 - Couldn't invoke servlet

After that xfire dies but tomcat continues working until I'll restart it.
How can I repair this exception?
