Subject: Re: CRITICAL: NULL Pointer Dereference in html_to_ascii() Causes Server Crash Loop
Interesting bug. We would have preferred if you included a stack trace, but in this case I was able to immediately reproduce the bug using the method you reported.
A fix has been committed, and is currently available via Easy Install. Container packages arriving shortly.
UCG seems a little unstable. I got booted a little while ago, just logged back in and with only 3 other users I assume citsrever must have respawned.

At 2:56pm (US Eastern time) watchtower upgraded Citadel and restarted the server. I've gotta figure out how to make that happen during off hours.
Subject: Send messages with registered date one hour after.
Dear All,
This is happening to me.
I think that is happening since the last upgrade (some days ago) when I send a message it has the date one hour after I sent.
I only noticed now. I upgraded at 6 Nov, 17H39 Central Europe Time. I can verify in some emails in the "Sent Items" after that (6 Nov) are registered one hour after than when sent.
Happens with all the emails clients.
Are this happening to someone else?
Thank you,
Luís Gonçalves.
Subject: Re: Concerning tha last two posts in Support Room.
Dear All,
Concerning this problem I improved the realibility of Citadel doing the following.
I noticed that the available memory (with "top") was not too much (some tens of Megabytes) and it had a lot of Buffer/Cache Memory. And the Swap has about 200 MBytes or more.
I suspected that when Citadel needed memory was not freed fast enough. Then I remembered that in Apache, I has configured disk cache with some time out to free it.
I disallowed the disk cache in Apache and the time out. I noticed that now I have more free memory (hundreds od Megabytes) and the swap is almost not used. Some times the free memory goes to more than a GByte showing that memory is freed.
Thank you,
Luís Gonçalves.

This night happened again. More coredumps. I updated the citadel. It installed and compiled a version but it remained the same version number. Did that attended my problem?
If not a send the new coredumps.

I hope that you solved or are solving this problem.
Let see that if or not happen again.
Unfortunately, your core dumps are not useful to anyone because they are specific to your citserver binary. I suppose if you include your citserver binary it might be useful, otherwise a stack trace is better.
In your case, we're just seeing so many weird things on your system that don't happen anywhere else. It's difficult to pin down why. I would strongly suggest that you give some consideration to moving to the containerized version of the Citadel system. It is lovingly built for you in a carefully controlled environment. Perhaps switch to the container version, and if necessary, do a ctdldump/ctdlload on your existing data.
And of course take lots of backups before doing anything.

But this tells us perhaps that we would be well served by detecting that kind of situation and saying something about it.
We already refuse to accept new messages when there is less than 100 MB free on the disk. Perhaps we need to look at memory too.

I have 3GBytes of RAM (all). 20GBytes Free disk. It is a KVM Centos 9 container. Basically it only runs Apache and Citadel. The Web page is not heavy.

3GBytes of Citadel Email data and only 2 email users.

I am having a problem getting the DKIM record to be recognised. If i create new public and private keys where can i find the files in a citadel system to install these keys.
/usr/local/citadel/keys/

You don't create the keys. Citadel does. It will auto-generate the keys when you set up your domain names in Citadel Server. Those keys will be posted to the "AideO" room. You copy those keys and put them in your DNS.
Citadel won't ingest DKIM keys that were generated by an external tool. You have to use the ones it supplies.
/usr/local/citadel/keys/
No, that's where TLS keys go. Not DKIM keys.
Dear All,
Until now when I sent an email with a new email address that email address was registed in the "Contacts" folder.
It is not happening anymore. I suppose that is happening since last Centos 9 update (with glibc (??) update, one of the Citadel dependencies was updated).
Notice that Thunderbird had also a recent update.
Is it happening with someone else?
Thank you,
Luís Gonçalves.
