[EquisMetaStock Group] MaxLocksperFile

I have Mdtastock 8.01 EOD, running on Windows 98SE. I have recently been running larger System Tests, and now when I go to Discard a test get a Program Error with the message: "file sharing lock count exceeded. Increase MaxLocksperFile."

I contacted Metastock support, and they showed me how to change this setting in the Registry. The "default" is 9500 locks. It was suggested to double or triple this. The technician I spoke to has his set to 250,000, but he also has Windows 2000.

I did some checking, and apparently a very high setting can slow down execution of some programs. I first increased mine to 20,000, and then to 40,000. If I run a System test with 100 stocks, 4 years of daily data, and 15 optimization settings (1440 tests in all), I still get this error message when I Discard the file. If I run it with 8 optimization settings, I can discard OK. (I select Discard and Clean-up after every system test, so their are no residual tests which Metastock is also trying to discard.)

The data for the system test is stored in ST_DATA.mdb. A file that is 43 Meg Discards OK. A file that is 71 Meg creates the error message.

Has anyone experienced these same problems, and if so, what MaxLocksperFile settings have been successful?

Having to run optimization tests with such a small number of variables so as not to trigger this error message is really labor intensive.
