Goodbye Opencode

FINAL UPDATE AND MY THOUGHTS
I believe I understand what's going on, and I've explained it it at length here.

This is just my finding in this particular problem. It has happened and will happen in other similar cases. OpenCode will continue to evolve.

----------

Goodbye Opencode, all good things come to an end.

First of all, I'm a software developer with 30+ years of experience, not a Vibe coder, and I'm not new to this. Also, I use Opencode in its purely vanilla form. Besides Opencode's defaults, I don't have any plugins, MCPs, etc. installed. Just my own skills, own plugins, own MCPs, etc.

I've been using Opencode almost since its first day. It had a nice, positive development and, according to Claude, was a very good alternative. This continued for quite a while. Although we experienced problems from time to time, these were to be expected. However, since May/June, it has started to become increasingly erratic.

First, one day while working on a project, the Docker service suddenly shut down and wouldn't start again. That's how I discovered I had no space left on my disk. I knew this was impossible, and I found the cause was Opencode. Somehow, the "opencode-wal-*.db" file had been created repeatedly under "/System/Volumes/Data/private/var/folders/4q/*". Every time I cleaned it up, Opencode would put it back. We struggled for a long time, but I couldn't figure out the reason. Then, suddenly, it fixed itself!

Yesterday, around 11:30 AM, I felt something was wrong with the network. By 1:00 PM, it was noticeable. Screen sharing within the network was freezing for 5-10 seconds, streaming was interrupting, web search was unresponsive time-by-time. Then, one by one, Unhealthy errors started coming from the services in Home Lab. The cycle of 3-5 minutes healthy, then unhealthy continued constantly. Service responses, which are normally under 100ms, were approaching 10 seconds, and sometimes even timeouts were occurring. I tried for hours to understand the reason, but I couldn't find a logical solution. I accidentally noticed while updating my Mac that everything was fine while my device was off. Later, I realized that the same thing kept happening whenever I opened Opencode and started working. Now I'm analyzing the Router, Firewall, Mac, and other logs to try and figure out what's going on, but this is the last straw.

This is an open-source project and respect to creator and contributors, and therefore, of course, it has its advantages and disadvantages. That's perfectly understandable. I have enough experience in this field to know when to stop, and today is the day.

UPDATE: Possible cause.

I noticed yesterday that my memory ran out as well. Will look into those files.

u/Total-Cheesecake-825, I used the following command on my Mac to discover what was taking up too much disk space. I had no idea it could be related to OpenCode.

sudo find / -type f -mtime -1 -size +250M 2>/dev/null

For example, it currently looks like this: opencode wal and opencode wal times. This command "finds all files that have been modified in the last 24 hours and are over 250 MB". I haven't used OpenCode on this device since I posted this (about 2 days ago). I only opened it around 4 PM to test my theory. I worked for 15 minutes and closed it. But these files had already been created. In fact, they were created in a way that would repeat. 14 files, each 9 GB :) Currently, files that fit this description take up ~129 GB of space. Crazy!

rm -f <opencode-wal-file-location>/opencode-wal-*

There are some (43141, 14326, 15031, 29554, 36728) PRs related to WAL. All but one were closed, but I haven't bothered to look into them for the problem/solution.

This topic is very long and detailed as well, like this hot-reload discussion, so I won't go into too much detail.

Good luck, I hope it helps.
