Hi


Recently i built a mailing application using JavaMail.

This application was developed on Win2K/Tomcat4.1.8 and hosted on Linux/Tomcat4.1.8 combination.

However, after a couple of successful attmpts to send mails with attachments, the system performance goes awefully low to the extent that even the simple login page gives a time out. I tried to retart Tomcat, but nothing changed. On restarting the machine, it did work ok for the first couple of requests again before going down to a trickle.



Any leads as to what should i check as the probable cause as I have no clues. Any test on Linux(i am newbie to linux) would be highly appreciated. For Windows versions too I need some pointers as I didnt get any proper replies from the JavaZoom support.


The jars are in the web-inf/lib folder.

Thanks,


Gunjan
