Not so fast...
Tomcat is indeed running out of threads, as the last INFO message indicates.
But this is probably more a *symptom* of some other underlying issue, as shown by the
previous exceptions.
Don't treat the symptom, treat the cause.

Hi Team,
We have .Net application consuming tomcat solr3.5 services and deployed on
Windows Server 2012. Its is 64 bit machine with 32 GB RAM and Tomcat
veriosn
is 6 and is installed at :"C:\Program Files (x86)\Apache Software
Foundation\Tomcat 6.0". During the peak load, the solr sevice
stops/unresponsive and it is happening very frequently. We didnt fount any
erro logs in windows event viewer but in tomcat logs we got the following
exception :
Aug 06, 2014 10:51:18 AM org.apache.solr.common.SolrException log SEVERE:
ClientAbortException: java.net.SocketException: Software caused connection
abort: socket write error at
this is ClientAbortException, happening (as the chain below seems to show) when the
application is trying to write a response to the client (presumably the user browser).
This generally happens when Tomcat tries to send back a response, but the client has
already closed the connection. Which in turn may happen if the client has been waiting
too long for this response (more than 2-3 minutes).
(It can also happen if the human user of that browser got tired of waiting, and clicked
somewhere else, or closed the window).
But a web application should not normally take so long to respond (or at least not without
letting the user know that it can take long, or provide some kind of feedback while the
user is waiting).
So again, there is probably something else going on..
