The store locator function on a national pizza chain's web site would completely hang their web server whenever an international search was done. Many, many hours and days of testing and debugging led us to conclude, and build a proof that it was a reproducible bug within IBM's Domino platform, only on AIX boxes, only when:
1) A script using LotusScript, their proprietary language was kicked off, and...
2) A Java agent was then kicked off before the original script completed.
At the time, Java was a new feature within that platform, so there weren't many apps that mized both languages.
After getting to this point, IBM joined in the fix effort, and we had daily conference calls, on which we always had IBM execs lurking because their 6.0 release of the platform was imminent, and this bug had the potential to wreak major havoc if not fixed before launch.
So I cannot personally claim to have done the actual bugfix - the IBM programmer did that. But it was a great learning experience to work together with IBM to find and fix it.
