@Bernard this has nothing to do with open or closed systems but one thing I must point out is that it seems you need to understand a little more about how the MySQL internals work. That database error you talk about can be caused by no disk space (Linux installs have a lightly different message). No disk space can actually shut down MySQL hence the reason you get the unable to connect to database.
So IEBC's claims of running out of disk space is quite valid and depending on how the server is setup it actually happens more often out in the real world than you think.
If you dont know what you are doing when setting up your database you will be shocked to find out that merely deleting logs will not free up this space. It is still possible to clean up this space but its a headache and the server would have to be brought down, assuming MySQL actually owns the space. A simpler method of optimizing is to set up the server with innodb_file_per_table option.
All-in-all we can just speculate for now.

As usual - any technical debate eventually loses issues and descends to open source vs closed source.It is not in order to allege the issue is the openness of the code or the operating system in use without knowing the facts.

(And great job with the http://results.uchaguzi.co.ke/index.php/senator.)
This can never be a disk space issue... the error gives it away:
"Database Error: Unable to connect to the database:Could not connect to MySQL"
It's a case of using Windows 2008 server - without tweaking - when a LAMP server would work out of the box :)
Which points to the bigger problem of using closed source systems for public interest software.
After paying KES 9B (or some happy figure) for it, and with the very detailed RFP in the public domain, IEBC should be able to own the software. They should open-source it - since it's paid for with public money. (I understand it is still proprietary to IFES)
For such a system, the cost of implementing the solution far outweighs the price of the software, so IEBC will still pay a lot of money for it. However, we get better quality, future-proofing and some savings (in future elections). Biggest payoff is the trust engendered by openness.

IEBC will process.
I believe we have skills that can handle that system. Let's give IEBC
benefit of patience they sort themselves out.
