I had a bit similar problem - see How to limit time for Connector
threads? tread in this mailing list.

In the end I found that my thread is in
java.net.SocketOutputStream.socketWrite0(Native Method) method. Probably
reason was that server waited for timeout because client had broken
connection.

Stack trace of running threads was very useful.

 The main problem is that there is no load on the serever when this
occurs.
 Everything works perfectly during the normal working week. The message
and
 the hunging occurs during weekends, when there is low traffic.

 Hi,
 it means that all threads are currently performing some request.
 
 It can have two reasons:
 
 1) High load of the server - requests come quicker than they are
 finished. You can increase maxThreads or you can look into your app
 why it takes so long time.
 
 2) Some requests are not finished due to some bug in your app. On
Linux
 you can send kill -QUIT to your Tomcat process. You will receive
stack
 traces of all VM threads and you can see where the threads currently
 are.

  Subject: All threads (150) are currently busy
 
  After several days of good woking my Tomcat 5.0.16 on RedHat 9.0
box
 stops
  accepting connection on SSL connector. In catalina.out I am
recieving
 this
  message:
 
  SEVERE: All threads (150) are currently busy
 
  My server.xml file for SSL connector is the following:
 
  Connector port=8443
 maxThreads=150 minSpareThreads=25
 maxSpareThreads=75
 enableLookups=false disableUploadTimeout=true
  connectionTimeout=2
 acceptCount=100 debug=0 scheme=https
 secure=true
Factory clientAuth=false protocol=TLS
 keystoreFile=***
  keystorePass=***/
  /Connector
 
  I tried to put smaller connectionTimeout but it does not work too.
 
  I am not able to find anything on Google.
 
  Thanks

Really sorry for the previous mail. I have sent it by mistake. How did you resolve the 
problem. I have visited the thread you have suggested, but however I was unable to 
find the solution.

I have made tests of my solution. It runs more then week without
problems. So, I have posted it now to the original mailing thread.

But it solves only my particular situation. I am not sure if the
solution can help you.

I think that more usefull for you is the way I found the problem. I used
kill -QUIT signal and from stack traces I recognized the reason (many
thanks to Antonio Fiol).
