Proof of principle ;-)

I'm running ELOG since several years with rather heavy usage.
Last week I've upgrades from 3.0.0 to 3.1.0 and this week I had twice the same problem:
elogd lost the index for old entries and showed empty logbooks, without having restarted.
The logbooks appeared to be empty; new entries started with index "1".
The first time the origin of the problem were network troubles;
the second time it had been caused by a severe problem of our AFS file system service.
I never experienced this consequence for ELOG in the past when we had AFS problems.

Since the logbooks are used for the operation log of a user facility they continued to do new entries.
The next day I had to re-number the new entries and restart elogd and everything was fine.

I could understand if elogd crashes when the filesystem of the logbook goes away.
And when it restarts with an (temporarily) empty filesystem, that would explain what happened.
But it did not restart and the log file does not contain any information about any problem, 
just that suddenly all new entries in each logbook started with ID "1" again.

Stefan, any idea?
Anyone else ever experienced that with the new ELOG version (or older ones)?

The downside of a script is, that it needs to execute on the server: you need to have the proper syntax for the shell of your operating system.
Here's a little example for a bash shell script, just to give you an idea (that would be for Linux, I have no experience with Windows):

Allow HTML = 1
Attributes =  person, mood, color
Default encoding = 2
Options person = John, Bill, Kate
Options mood = calm, upset
Subst color = $shell(if [ "$mood" == "calm" ] ;then echo "green"; else echo "red";fi)
Change person = <font color="$color">$person</font>
List Change person = <font color="$color">$person</font>
Show Attributes = person, mood
Show Attributes Edit = person, mood
List display = ID, Date, person


Disclaimer: When I've tested it locally the HTML was displayed as source. Stefan, any idea? (ELOG V3.1.0-5be245e)

I think that this is neither possible nor reasonable. Of course everything is possible with shell- and java-scripting, but that would be a software
package on top of ELOG.
Keep in mind we are talking about an electronic logbook here, not about a relational database.
