If second one is right then your issue is not really on the place what you are getting in your LOG. It may differ each time upon your request. I am not sure if i am able to make you understand the point.
Here I am breifing one of my experiencing on one of our application. After launching the application first 6 months there was no issue as planned we needed to restart it every night. but after 6 months when more loads started to come it used get terminated 5 to 6 times a day after Out-of-memory error. And mostly we used to get error message from our LOG file regarding one specific funtion point. So people started to dig into this area. everybody tried the same in myDevelopment Box but could not reproduce it. So one day I used JMeter(open source to do load testing) to capture the script. Then tried to put load through it and was able to reproduce it. After lot of inspection I find out main issue with session. In that application a lot of data is being stored into session. So more user loged in more memory is used. And if user close the browser without logging out session used to be there as it was having 1 hour session time out as per business recuirement.So we did tuning with session and issue got resolved.It may give you some idea.
Anyway can you ans me which one is right out of my two Q at the begining. Depending on your reply I may try to give you the solution.
