hi all,
we were stress testing our app today with real users
and found that at high loads some users were winding
up with others' session info. as we autopopulated
text controls with previously entered information,
some users found that info entered by others on other
client machines was popping into their screens. has
anyone else seen anything like this before?
the stress on the server was particularly heavy as we
were running a trace logger at the time, which of
course involved serious i/o pressure, so this wasn't
in response to particular user load (about 10 people
executing fairly involved searches). as soon as we
shut down the trace function, the problem disappeared,
but we're worried that once we get 100-200 people at
once onto this app that we'll have problems again.
we thought that perhaps request dispatcher might be
the root of the problem. does anyone know if it is
supposed to be thread safe?
any other ideas?
we're running orion 1.1.37 on redhat linux, using the
blackdown 1.2.2-RC4 jdk/jre.
thanks,
bradley mclain
