Title: Y2K Aftermath and a Hard Day with Apache

---

June 11, 2001 was just another day for me in the wild world of operations. I remember it as one of those days when you can’t help but think about how much technology had advanced, yet still struggled to keep everything running smoothly.

Y2K Aftermath and Legacy Code

You see, we were dealing with a lot of legacy code back then. Our servers ran Apache 1.3 (a version from the previous century) alongside Linux on old hardware. Yes, I said “old” — those were days when the latest and greatest meant running RHEL 6.2 (now that’s ancient by today’s standards). We relied heavily on Sendmail for email, BIND for DNS, and MySQL 3.23 for our database needs.

Y2K had passed without any major issues, but it left behind a legacy of constant vigilance. Every time someone mentioned “date handling” in the context of software, my heart would skip a beat. We were already starting to see some early signs of the Y2K lessons coming into play with new versions of these tools being released.

A Debugging Session

One particularly challenging morning started like any other. I was monitoring our servers when I noticed something peculiar: Apache was crashing every few minutes, and the logs weren’t giving me much insight. This wasn’t a typical segfault or memory corruption issue; it felt more like some kind of internal timing problem.

I spent hours digging through code and logs, trying to pinpoint what was going wrong. It turned out that in Apache 1.3, there were subtle race conditions related to the way it handled requests and child processes. Specifically, a timeout setting in our configuration was causing problems because the parent process wasn’t properly handling the signal for child process management.

The solution? Well, it wasn’t glamorous. We ended up patching the source code ourselves and compiling a custom version of Apache with a different timeout value. It wasn’t ideal, but it worked until we could upgrade to a newer version that fixed these issues.

Early VMware and Virtualization

While battling Apache, I couldn’t help but notice how virtualization was starting to become more mainstream. VMware had just released their first public beta of ESX (now known as vSphere), which promised better performance and flexibility than traditional physical machines. The thought of being able to run multiple instances of our stack on a single machine without worrying about compatibility issues was exciting.

But, like everything else in tech at the time, it wasn’t all smooth sailing. We had to deal with compatibility issues between different versions of software running in virtual environments and figure out how to manage these new machines effectively. It felt like we were constantly walking a tightrope between innovation and stability.

The Realization

By the end of the day, as I sat in front of my monitor staring at an almost empty Apache log file, I couldn’t help but reflect on the journey we had been on. From Y2K to virtualization, each step forward seemed to come with its own set of challenges and learning opportunities.

In those early days, it was all about finding ways to keep our systems running smoothly while embracing new technologies. It wasn’t always pretty, but it was rewarding. Each problem solved brought us one step closer to a better infrastructure.

As I turned off my computer for the night, I couldn’t help but wonder what the next big challenge would be. Would it be another race condition in Apache? Or perhaps a bug in BIND caused by IPv6? Only time would tell.

But until then, we had our work cut out for us. And that’s exactly how I like it.
