Re: All threads (150) are currently busy....

Hi Pavle,

Do you use a database?
Is there a firewall between Tomcat and the database?

If both answers are "yes", try using testWhileIdle, validationQuery, time between eviction runs (can't remember property name) and other DBCP properties.

Other than that, my typical advice, which I learnt from Yoav Shapira IIRC, is (as Lipi told you), kill -QUIT and see what happens.

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.

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="20000"
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

Pavle
