Re: Too many users
you might also want to check your application with OptimizeIt or a similar tool to see if it is leaking memory. Also if u have static pages or jsp pages that dont change often, you can explore the possibility of caching them.

Re: Too many users
First of all, this has nothing to do with JSP. Nevertheless, it's obvious you need to add more memory. That's a cheap and effective solution for a simple situation like this. > -Original Message- > From: Deepak [mailto:[EMAIL PROTECTED] > Sent: Thursday, March 06, 2003 5:28 AM > To: [EMAIL PROTECTED] > Subject: Too many users > > Hi > > I am in a tight spot.

Too many users
Hi I am in a tight spot. Hope someone can help me on this. My Webapp uses: 1. Cobalt Linux server 2. Jdk1.4 3. Tomcat 3.3.1 4. MySql 3.51 200+ users access my webapp. After some time my server hangs and I am not able to telnet , ftp or access the webapp. The server guy says that too many java processes are running. I did the top command and I got this o/p regarding memory. Mem: 255508K av, 252176K used,3332K free, 0K shrd, 0K buff Swap: 524536K av, 524536K used, 0K free 7312K cached Total RAM is 256 MB Total swap memory is 524 MB As you can see 100% of swap memory is used up and almost 98% of RAM is used up. Is it because Tomcat will generate 200 threads if 200 users issue a request ? Why am i not able to connect to the server after this? Please throw some light on this issue.
