Proxy maxServerTransactions parameter

Hi,

I use the proxy of the jain-sip-presence-proxy project to establish SIP 
sessions between several applications.

I establish a session between two applications, then I close it. If I do 
it severals times, the proxy returns a "500 Internal Error".
I have notice that this problem is due to the maximum server 
transactions parameters. If I increase this parameter, it solves the 
problem.

What I want to know it's what are the consequences on the proxy. I have 
noticed that 20 transactions is the maximal value with the graphical 
configuration and I have increased the parameter to 200.

Thanks,

Jean-Philippe
