However, just to re-confirm in my particular case disk is no issue at
all. I have around 470GiB free on the file system where the database
resides. So question is still how I can understand what causes the
SIGSEGV crash on the citadel server. 

If you have a core dump you can do a stack trace against it. If not, you can run citserver in the debugger. Like this:

systemctl stop citserver
cd /usr/local/citadel
gdb ./citserver
gdb> run -x9
[ wait for it to crash ]
gdb> thread apply all bt

Then post the output here.

With some logfile watching I was able to track the issue back to two iOS devices. As soon as these start syncing IMAP the server crashes and executes automatic restart. I disabled the devices and did export and re-import of database. Server was stable after. Re-nable on device was triggering the crashes again. Went then and updated server to 1011. So far server has not crahed again even with the Apple devices synching. Will watch, let's hope this did the trick.  

Dear All,

I am getting again message not found errors in the syslog:

Believe ther was a way to target and remove these message references from the system using the console interface but I can't recall how this was done. Also did not find this in the documentation. Can somebody remind me on the procedure, please.

Thanks! 

Hi Ignatius,

but where will it be defined ? First start citadel, it will defined in a config that starts webcit with parameters X.

What you mean with [other options] ?

WebCit is normally called with options to specify the port number it's listening on, whether to enable HTTPS, and the directory where Citadel Server can be found.

For example, here are the commands we are using to start WebCit here:

webcit -x1 -s -p 443 -g /dotgoto?room='Welcome to UNCENSORED!' uds /citadel-data
webcit -x1 -p 80 -g /dotgoto?room='Welcome to UNCENSORED!' uds /citadel-data

(Most sites will have two, one for HTTP and one for HTTPS, but if you have Citadel sitting behind a proxy or if you have some other webserver redirecting HTTP to HTTPS you might only have one.)

Sorry for the dumb question :)

There was a missing Information to edit it in systemd.

nano /etc/systemd/system/webcit-https.service

Hi there,

i got problems with insert links after update to 1011. Same here...

Greetings

Mike

Good Night (here),

I use Thunderbird as email client.

Due to I am being now unemployed I send lots of emails advertizing me. I use an email template and the plugin/extension Merge to send a batch of emails.

When I send a batch of several emails and store the template email in a folder in the citadel server I notice that I have only access to about 40 emails addresses (i.e. when I do a reply to all from the email template) when the template have much more than 40 destinataries. When I store in a local folder or in another email server (e.g. Microsoft Exchange) I have access to all the emails addresses. 

I suppose this is a limitation of the Citadel Email Server.

It is normal that I send batches greater than 100 emails each.

Could it be solved?

Thank you,

Luís Gonçalves.

Maybe try from another browser or clear your cache?   It seems to work for me.

I believe there is a limit of 1024 characters.  I don't quite remember whether that's in total or for each of to/cc/bcc, but it's a character limit, not an address limit.

Good Afternoon,

Cloud you please increase to say 4096 or 8192 charaters instead of 1024?

Or it has difficult implications on the database?

Thank you,

Luís Gonçalves.

I hope this time I am not being rude. Thank you.

Since updating to 1012, the first access of the website issues a 503 error:

This program was unable to connect or stay connected to the Citadel server. Please report this problem to your system administrator.

If you reload, it works and stays working.  If you navigate away for a while (half hourish?) and go back you get the error again.

In the log, I see a message like:

This is a private/testing instance so I'm the only user, so I can't comment if other users have this problem.

I am not sure if I broke something or it's a regression from 1011 to 1012

Thanks!

Do you have set a Session limit in the options ?

I just double checked and concurrent session limit is set to 0.

Thank you

Got same Error and set befor session limit to 50. After setting to 0, i got no error anymore.

So ... did changing that to some nonzero value fix it?
