Thanks Roel.
I am still running into this error. After investigating the link, it seems the
documentation indicates a known issue but does not offer a workaround.
The command I am running (including the addition of a --mask parameter) is:
./runall.pl --grammar=conf/partitioning/${grammar} --duration=${secDuration}
--queries=${numQueries} --threads=${numThreads} --basedir=${BASEDIR1}
--vardir=${VARDIR1} --mask=1000 ${debugSwitch} ${sqlLog1} --sqltrace
Do I also need a "--mask-level" argument to address this issue?
I think I need some additional clarification as to what masking does and how to
address these errors in my test run.
Should I completely remove the range_elem portion from my .yy file?
Thanks,
Joel

Hi Joel,
Are you using Grammar Masking? Have a look at " Known issue with grammar
masking " within;

Hello,
I am seeing this error while trying to run the partitions-99-range.yy grammar
file:
Rule range_elem occured more than 3500 times. Possible endless loop in grammar.
Aborting.
When I examine the grammar file, I can see that there are recursive calls from
range_elem to range_list_elem_10 to range_list which could generate a large
loop. But it doesn't seem like it would be an endless loop. Is there a
setting on my system that could be preventing these expressions from evaluating
within the grammar engine?
Thanks,
Joel
