New issue 352 by bugspot: Robot Framework HTML log generation hangs after
testing is complete.
http://code.google.com/p/robotframework/issues/detail?id=352
Running the attached script and looping 5000 times on various systems hangs
the log generation process. The XML file looks intact.
The attached script is intended as a stress test on a base host system.
System 1 and 3 hang in the command window without errors. System 2, which
has more memory and CPU power generates error messages.
In all cases observed, the memory and CPU are stable while running the
script. System 1 & 3 use about 38 - 40% CPU and 8648kB memory, System 2
reports 32% CPU use and similar memory use. Log compilation then increases
the use of each.

/******************************************************************/
Report from System 3 (Linux) Test:
When I ran 5000 loops of your test program, it was CPU bound during the
actual test, then switched to disk bound. The CPU bound phase, which
coincided with the writing of output.html, took exactly one hour, from
20:24 to 21:24.
It is still in the disk bound phase after more than 2 hours. The disk
activity is almost entirely due to swapping, with nearly 1 GB of physical
memory and nearly 1 GB of virtual memory in use. I discovered that by
turning off an energy saving feature (athcool) in the CPU I could improve
system response considerably, but here it is close to midnight and it is
still chugging away.
I noticed that the only file written during the CPU bound phase was
output.xml -- about 400 meg. I suspect that the program is in the process
of creating the html outputs, but is formatting them in memory before
writing them to disk. If the machine had about 2 GB of physical memory,
that would eliminate swapping and make this go orders of magnitude faster.
With 1 GB, it might work better if Robot Framework wrote the HTML directly
to disk, instead of formatting in RAM since that is actually disk in this
case.
