Subject Tomcat ajp connections stuck in service mode
Date Mon, 21 Jan 2008 15:59:26 GMT

Hi Guys



I have tomcat 5.0(shipped as part of jboss 4.02), and this has a static
web context set up within the tomcat server.xml


<Context docBase='G:/figs' path='/fig'/>  


This works fine for long periods, but for some unknown reason, this web
context mapping seems to get stuck and fail to service all the files
within the G:/figs folder back to the client.    The web application
then gets stuck using all the jk connections.  Tomcat still listens to
requests, but fails to respond and just hangs.  The docbase G:\figs is a
network mapping to a SAN.  


An example of the status( all 400 threads are used by similar URLS - all
going to the fig web context).





Max threads: 400 Min spare threads: 4 Max spare threads: 50 Current
thread count: 400 Current thread busy: 400
Max processing time: 2271757 ms Processing time: 688574 s Request count:
2034097 Error count: 104644 Bytes received: 0.00 MB Bytes sent: 46928.70

I really do hope someone has encountered something like this before??


Very much appreciated if anyone can shed any light and help.


Thanks in advance.
