Dear all,
Hope I can find an answer here. I'm using latest Selenium Grid 1.0.6
with Testng framework.
I'm automating a user journey by feeding content from text files to
the same selenium script (in Java), so it is a repeated test with
different test data. Say if I have 50 text files, then there will be
50 test runs using the same selenium script, and they run
sequentially. However, I bumped into this problem where the test
stopped arbitrary and giving me Internal Server Error. Arbitrary in
the sense say it stopped at test no. 30, and in the next attempt it
stopped at test no. 12, so on and so forth which leaves me no clue
what the problem is.
Does anyone has similar problem here? Hope someone could shed the
light on this...
Thanks.
Ann

Things I've seen cause this include a malformed URL in the test script
or the selenium server (RC) shut down. I don't know if these might
solve your problem.

Hi Andrew,
First, thanks for responding.
On each attempt, the 50 test runs I mentioned earlier were using the
same URL over and over again, so if it's the URL malformed problem, I
would have thought it wouldn't run at all in the beginning. The
problem being of the 50 test runs, it stopped arbitrary, sometimes it
completed the 50 test runs and sometimes it didn't leaving the RC
stuck in active state and browser (tried on safari and firefox)
remained open. I will then have to quit them manually.
I thought it may have to do with java heap size thus I increased it to
256M (default 125M), but it does not help.
While trying it out more times, I now get to see other errors related
to selenium sessions:
<pre>
java.lang.RuntimeException: Could not start Selenium session: ERROR:
Could not retrieve a new session

Hi Ann,
when this problem occurs, check the memory (Windows Task Manager -->
Applications --> the_browser_in_use). Most probably you will see that
it is very high (close to 700 Mb of RAM) and this might cause the
Internal Server Error (A clumsy way of saying "Unable to load
browser"). Let me know if this is the case, I might offer a few tips
to prevent it.

Hi Ayhan,
Thank for helping.
I noticed the memory used for Hud, RC, and browsers were never above 110M and so now I rule out the memory problem guess I made earlier.
Having said that, this problem still remained. However, I noticed whenever this problem happened, no error log seen on Selenium RC nor the console where I run my test, but when I traced back the Hub log, I did see the following two types of error appeared on the Selenium Hub log:
Error 1:
