Hi All, 

As i am getting below error when JMS getting stopped automatically with the
following error(It's happened twice as of now and that too only one day in
business time). We are using Tomcat server in our application

javax.jms.JMSException: No buffer space available (maximum connections
reached?): connect

We know work around would be, we need to restart the JMS but if this happens
every time in business timings then it might be a big problem for us.

So can any one help me to understand the issue in detail for my questions
below.

1)what would be root cause for the issue. 
2)In what scenario's this situation raises
3)what would be our precautions to avoid this error. 
4) what suggestions we can provide to getrid of this error

Please suggest asap which helps me alot

Thanks in advance...

Regards,
Venkatesh
