What was the worst bug you've ever solved ?
rm-rf: Worst software bugs, in increasing order of severity:An ASP.NET app that didn't consume it's record sets before closing it's database connections, thereby breaking IIS's connection pooling and causing hundreds SQL server login/logouts per second. Lots of interesting side effects on that bug.An obscure page latching problem on a high volume SQL server (hundreds of transactions & thousands of queries per second). The SQL server would spend all of it's time waiting on page latches, response time would grow exponentially. An eleven hour phone call with MS support finally identified the problem.Oracle 10.2.0.[1234]
