How to resolve Bad File Descriptor

[Tim-K5AC]

I am getting an error when I try to start the daemon.

Error AqualinkD: Error reading config file '/etc/aqualinkd.conf'
Bad File Descriptor: Error reading config file

I have edited the config file and it seems fine and renamed it and tried to restart with the new name...same error

I have done multiple aqua.sh clean and reinstalls and I still can't get this error to go away.

Any ideas would be appreciated, this died right before our freeze and I need to get AqualinkD running again ASAP.

Thanks

Seems like you have tried everything I would have done.
That error can be from a CF card going bad, or too many open files.
A reboot will fix too many open files.

Moving the file out the way and creating a new one might be the way to go.

cd ~
sudo mv /etc/aqualinkd.conf /etc/aqualinkd.conf.bad
wget https://raw.githubusercontent.com/sfeakes/AqualinkD/refs/heads/master/release/aqualinkd.conf
sudo mv ./aqualinkd.conf /etc/aqualinkd.conf

Moving the conf file didn't work, still got bad descriptor, so I reformatted the SD card.

I got an error when I tried to install, says version.h is missing. Did the install abort after this or was it ok? Did something not get checked in?

Below is the snippet of the attempted release install.

pool@raspberrypi:~ $ ~/aqua.sh release

That looks like it installed. The No such file is odd, I'll have to check that, but that error wouldn't have halted the install.

I’m back up and running, I just need to recreate my schedule. Thanks for your help. These Pi’s are pretty brittle. I guess I need to put it on a small UPS or battery!

It’s the CF card, if you make it read only root file system, it’ll run for years without issue. It’s mentioned in the wiki. But if you Google “raspberry pi read only root” or “raspberry pi overlayfs” their are plenty of options.
I’ve been playing a lot with a few raspberry clones that have eMMC recently. They are way more stable since their is no need for a cf card, ill be posting about my findings in a month or so.
