  68872   Wed Dec 12 10:44:57 2018 Warning Antonio Iulianoantonio.iuliano@cern.chQuestionLinux3.1.2xmalloc error when filling entries and chaning page

Dear ELOG experts,

the ELOG server on our lab crashes  continuosly, when we add a new entry or even if we click the arrows to navigate between entries. Following the FAQ on the website, I have used gdb and found the following error:

xmalloc: not enough memory

[Inferior 1 (process 23271) exited with code 01]

It should be then some allocation issue when we try to access to the entries, but I could not figure the nature of the issue. I was, however, able to reproduce it with a fresh ELOG installation and the same configuration file (ELOG cloned from git and installed today)

Could you please give me any suggestion? I attach here the configuration file we use.

Best regards,

Antonio Iuliano

  68873   Fri Dec 14 15:46:14 2018 Question Frank Baptistacaffeinejazz@gmail.comQuestionWindows3.1.2Logbook architecture and availability

I have a setting which makes ELOG a perfect solution, but there's a situation that I'm struggling to get my head around. We have 3 separate laboratories, each one containing a number of temperature chambers, which run almost constantly over a number of shifts. Each temperature chamber has it's own logbook (laptop). So far, pretty simple.
My dilemma is, our network goes down for maintenance/updates (more often than I'd like), but our operation cannot afford to stop during network interruptions.
With that said, I thought about whether I could run a "local" logbook on each laptop/chamber, and somehow mirror the local logbook to the main ELOG server.
Perhaps I'm over-thinking this...do you have any recommendations?

Sure that's easy. Install elog on each laptop separately, so they run without network. Then, set up a central elog server, and use "mirroring" as explained in the documentation at https://elog.psi.ch/elog/config.html#mirroring

So when ever the entwork comes back, you execute a manual mirror operation, and your new entries will be pushed to the central elog server.

Best,
Stefan

Thanks Stephan! I guess I was making it harder than it is.  I'm still a little fuzzy -- in this instance, am I correct in saying that each laptop would be considered a "master", and the remote (network) server considered the "slave"?  Also, I'm not sure quite sure -- which server should be assigned responsibility for performing periodic synchronization between the laptop and the central elog server?

Thanks again for all you do -- Happy Holidays!

I would call the laptops the "master" being responsible for pushing data to the central server which you can call "slave"

I tried to reproduce the problem but could not. The config file uses "emtpy.html", "filtermenutext.html" and so on which I don't have. Same with eventlocation.

Rather than sending me all the files, can you strip down your elogd.cfg to a minimal version where you still see the problem. Then give me all information to reproduce it. You also have to tell me when the error occurs, like when you submit a new entry, scan through entries etc.

Dear ELOG experts,

the ELOG server on our lab crashes  continuosly, when we add a new entry or even if we click the arrows to navigate between entries. Following the FAQ on the website, I have used gdb and found the following error:

xmalloc: not enough memory

[Inferior 1 (process 23271) exited with code 01]

It should be then some allocation issue when we try to access to the entries, but I could not figure the nature of the issue. I was, however, able to reproduce it with a fresh ELOG installation and the same configuration file (ELOG cloned from git and installed today)

Could you please give me any suggestion? I attach here the configuration file we use.

Best regards,

Antonio Iuliano

I've got things working - sort of.  Ran into one strange problem that has me scratching my head.  I have two different laptops, each running a local instance of their own logbook.  Both are functional, but for some strange reason, one looks great, and the other is missing its graphic format.  I've attached a screen capture of that logbook, and a copy of the config file.  Do you see something that I've done wrong?

Thanks,

Frank
