f it is working in the LoadRunner scrīpt up to a point, then the problemprobably(see footnote 1 at end of post) exists in the system under test. Are
you or anyone else monitoring the system under test? The first places
to look would be at the web and app-servers:51Testing软件测试网'jvg*f7LfVJa
1) heap sizes

is still a chance that you may be contributing to the issue on your end
(not to say the sys-under-test is not the issue - and that it may
require tuning or scalabiity work in 2 dimensions), depending upon the
answers to the below questions AND the computing power/configuration of
the servers-under-test...51Testing软件测试网#r6o3b$hs L,@r6K
