Chilisoft restarting - how can I found out why ?

I am running Chilisoft 3.6.2 on a Sun Cobalt Raq XTR with 1Gb of memory and chilisoft is restarting every hour or so. The application connects to a MySQL database and most pages make DB calls but the connection is closed and set to nothing on every page.

It does not seem to be a memory issue as just before it restarted last time the output from free -m is:

Wed Feb 12 11:46:01 GMT 2003

total used free shared buffers cached
Mem: 1010 598 412 419 380 56
-/+ buffers/cache: 161 849
Swap: 128 0 128

What I need to

I received a message at 11:46 saying the ASP server was restarted. Entries from the server diagnostics around this time are below:

What I need is to be able to understand WHY it is rebooting. If I knew it was because a connection limit had been reached or there was a memory problem I could look further but until I can narrow it down I have no idea why it is reseting. The response seems to slow down before a restart so I think it is lacking in some resource.

The output from the server monitor shows:

Total requests 2021
Requests per second 3
Total errors received 0
Current number of sessions 168
Cached scripts 243
Active virtual hosts 3
Total memory in use 64292KB
Uptime running for 0.31 hours

It seems that the number of sessions and cached scripts just keeps increasing. Is this correct ? I have Cache Scripts turned off in the settings so a little confused.

This is a problem on our live server so have not had much sleep. Any help would be great.

Thanks,

Chris

Sorry - It's actually version 3.6.0
