Dear Stefan,

Thanks for your reply.

I started running elog in February and it never failed. Then it started failing regularly towards the end of September. There were no system changes until then, except the daily automatic Yum updates (SLC4). Then I upgraded to the latest version (tar ball of 2.7.5). Then yesterday it crashed again. I saw that it crashed around the time when a user was doing something - inputting new data. I can monitor when it crashes and correlate it with user activity. But it is not easy to reproduce since I don't know exactly what the user is typing.

It would be necessary to record the user input forms and then replay them against a known server state. But that is not so easy.

I will think about doing something else - maybe running inside a debugger as you suggest.

Hi

 I am experiencing trouble with Elog crashing. I think it crashes during input operations (new entries are being added).

Are there any preferred methods to troubleshoot this ? Any log files I could look at ?

For now, I let "monit" supervise the process and restart it if it crashes. But I would like to get to the root cause of the problem.

Dear Soren,

sorry for the trouble, but it's very hard to diagnose this remotely. This forum here runs fine for many months, so in principle Elog should be stable (at least the current version 2.7.5). If you have an older version, please upgrade. If you have a way to reproduce the problem reliably, you can send me your config file and explain step-by-step how you make Elog crash. Then I can try to reproduce it here. Otherwise the only chance I see is to run elog from inside the debugger, and once it crashes record the stack trace and send it to me. If you don't know how to use the gnu debugger, I'm sure you find someone at CERN who knows. 

Best regards,

   Stefan

 Just run it inside gdb. When it crashes, you will see a segment violation and you will end up at the debugger prompt. Then do a "bt" to see the stack dump. From that I can guess where the problem happens.

i have been using elogbook V2.7.6 on my XP machine for a number of years. I ahve recently upgraded to windows 8 and the reply function on my entries has changed. I can now see the previous entrys in HTML format rather than the reply box which used to appear and also my ability to upload attachments and paste working linls is removed. Do i need to upgrade to the latest version and do i ned to back up my previous entries and how do i do this?

 

Thank you

Upgrading Windows should not change the behavior of ELOG, unless you made a mistake during re-installation of ELOG. Can you post a picture on how your reply looks like, it's hard for me to understand what you write.

I've managed to get it working and the problem wasn't what I thought it was.  It turns out that ImageMagick v7 doesn't have a "convert.exe" program in the windows version due to some conflict with a disk conversion utility.  The "convert.exe" has been replaced with a "magick.exe" and so I made a CONVERT.BAT script within the elog folder with content "magick %*".  This workaround appears to have solved the problem.

I was wondering if anyone would be able to assist me in getting the ImageMagick/figure scaling working on an elog running under windows 11 (Microsoft Windows Version 22H2 (OS Build 22621.3880)).   I've followed the installation instructions and checked that $PATH contains the directory for both ImageMagick and GSS.  In a 'command prompt' window, when I execute "identify -version" from any directory I get the response:

 

Version: ImageMagick 7.1.1-35 Q16-HDRI x64 d775d2a:20240714 https://imagemagick.org
Copyright: (C) 1999 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php

Compiler: Visual Studio 2022 (194033811)

 

which I believe is correct.  I've looked through the source-code for the elog and I believe that upon initialisation elogd is looking for a response containing "ImageMagick" somewhere in the response [image_magick_exist = (strstr(str, "ImageMagick") != NULL);] so I'm not sure I understand why this isn't being satisfied.  When I run elogd I get the statement "ImageMagick NOT detected. Image scaling will not work.".

I have the feeling that this is some security restriction in windows 11, so was wondering if anyone had seen this problem before and knew of a solution.

Many Thanks

No, there is no Dotnet or DLL required. Just start the ELOG server manually by clickin on Start/Programs/ELOG Server/Start ELOG server manually and watch if you can spot any error. One person reported that downloading again the package solved a similar problem.

 Thanks for the feedback, I found the problem, someone installed the AVG toolbar in Internet Explorer in the computers, and for some reason the AVG Error Redirection option prevents Elog from opening in Internet Explorer.

Previously, when we used 

Subst on reply subject = Re: $subject

The new "Re: " text would appear in the "subject" field while the user was editing their reply, and they could edit or delete it.
Since 2.7.8, however, it does not appear while editing, but shows up only after the user submits their entry. We would prefer that this appears while the user is editing, because in some cases we want the users to have the option to modify this text. Was this intentional? Is there a way to restore the previous functionality?[...]

Sorry, that appears to be an undocumented bug fix :-)

The desired behaviour should be created by

Preset on reply subject = Re: $subject

The command "Subst" is supposed to overwrite the field after it is submitted.

From the documentation you will even find a nicer possibility:

Preset on first reply Subject = Re: $Subject

The prevent replies to build a long chain of "Re: Re: Re: ...."

Thanks for reporting that problem. I just implemented Suppress email on edit and this could have had some side effect. I tried however to reproduce your problem and was not able to. Trying the "minimal" configuration file, the email notifications were suppressed if the check box was checked, or if Suppress default = 3. Can you check if it works with a minimal config file, and if yes, what option in your "full" config file causes this effect?
