Subject Re: exceptions/warnings during benchmark run
Date Fri, 30 Jul 2010 05:27:44 GMT
I did face similar problems long time back. I guess you are not
restarting your webserver which is possibly causing  the first issue
whereas to resolve the second issue I guess you need to maintain the
number of concurrent users same as the number for which DB is loaded.
I am not sure of the second solution but the first one should work.
