Has anyone had issues with having too many files open? I'll setup my server and let it go but after a while, I end up with a lot of "cannot create socket: Too many open files" errors being reported.  I have a sync to another e-log going which I suspect is part of the cause since that e-log server hasn't had this issue. I suspect that there are files being opened, going into some return loop code and then never getting closed. I'm not a C programmer but I see lines like :

fh = open(tmp_filename, O_RDONLY);
      if (fh > 0) {
         read(fh, result, size - 1);
         close(fh);
      }

      /* remove temporary file */
      remove(tmp_filename);

This looks like it opens the file but unless the remove function closes the file, it will remain open even through the file has been deleted. Maybe this isn't the correct behaviour of 'remove' and I am mistaken?

There are also parts like :

 fh = open(textfile, O_RDONLY | O_BINARY);
      if (fh < 0) {
         printf("Message file \"%s\" does not exist.\n", textfile);
         return 1;
      }

      size = (INT) lseek(fh, 0, SEEK_END);
      lseek(fh, 0, SEEK_SET);

      if (size > (INT) (sizeof(text) - 1)) {
         printf("Message file \"%s\" is too long (%zd bytes max).\n", textfile, sizeof(text));
         return 1;
      }
This looks like for the second error, it will complain that the file is too long, return an error message but not close the file and would leave it open. Is this a reasonable avenue to pursue or am I mis-reading the code?   Thanks.

We were running ELOG for many many years in our experiments and the instance was operated on a Debian XEN server as a container. I am now trying to migrate it into our Docker Swarm cluster and I am using the https://hub.docker.com/r/de1lz/elog-docker Docker image, which works very well with our logbooks when I run it as a single container. However, when I put the container behind my load balancer (HAProxy) using the simple HTTP mode (which works very well for all the other HTTP-based services) with this simple configuration:

backend be_elog.km3net.de
    mode http
    server-template km3net-elog- 1 km3net-elog_elog:8080 check resolvers docker init-addr libc,none

I get a "too many redirects" error when I try to access one of the logbooks. The starting page works fine, but every other link leads to a pile-up of redirects.

Here is the current instance running, where you can see the behaviour: https://elog.test.km3net.de (all log entries deleted and only two logbooks activated)

My question is: what kind of redirect could go wrong here? I don't know how the internal HTTP server of ELOG works, but maybe someone faced similar issues.

My ELOG configuration is also pretty basic, and as I wrote above, everything works when I run it without the load balancer (single instance at the moment). Here is the top part of the configuration, it contains a few dozens of logbooks but they are configured the very same way.

Hi,

One of my logbooks is a fault reporting system; it emails a group of people when a fault is reported. There is an MOption 'Technical Groups', and I want to have a tooltip for each checkbox which shows who is referred to by each group name. However, individual tooltips for each MOption attribute don't seem to work. I've looked at the HTML code, and there's no 'title' attribute for the checkboxes, so it's not a browser problem. I've attached my config file. Any idea what's going wrong?

Having "Top group" in a config-file for Windows will cause:

Internal error, no valid header!

Removing "top group" makes elogd.exe work. The error is repeatable and the same config file works on the same version of Elog on Linux. Elog was compiled with Cygwin.
