I have experience of elog hanging (under linux).  I'll describe my situation, although it may not apply to you.  I still use elog 2.9.2 but I am unaware of this issue ever being resolved although I have mentioned it in the past.  (Possibly because I'm one of the few who has this situation).  I certainly recall other person had this as the problem, and my reply on this forum solved their problem.  The cause is the following:

1.  A thread with a large number of replies - something over 40 I think.

2.  This long thread is deleted from the first entry.  This will crash elog,

3.  Once restarted, the later entries of the deleted thread (which survived the deletion attempt when elog crashed) are accessed.  This will cause elog to go into an endless loop and hang.  Until I learnt better, I had to reboot the computer.  Under linux kill -9 (process) does the job, but kill (process) does not.

The problem lays with the first entry that survived the attempt at deletion.  It has an "In reply to" line in the entry in the yymmdda.log file, referring to an entry that has now been deleted.  Manually editing the yymmdda.log file to remove that line does the trick, and then the surviving entries can be accessed and deleted.

A good work-around is that if you are about to delete a long thread is to delete it in sections, starting at the end.  It is useful to note the entry number or some other way to find it again after the last section is deleted, as of course it will now be back in with the even older entries.  Or have two tabs on your browser accessing the same thread.

If you want to move the long thread to another logbook, to avoid the problem, Copy the thread, and then do the deletion in stages.  Moving a long thread does the same computer crash/computer hang, although the Copying part is done fine, the deletion part is the problem.

You don't have to have a large number of replies to an entry to cause the hang in controlled conditions.  Just edit the yymmdda.log file of a new entry adding in a "In reply to" line referring to an earlier entry number that does not exist is enough to cause the problem when you try and access the thread.

If this is the cause of your issue, the problem is to find the orphan thread that is causing the hang, especially after all this time.  Also, you may have more than one orphan thread.  Even though I am aware of the problem, I do occasionally find orphan threads in my logbooks.  In my case I use the ticketing system, and searching by ticket number will find an orphan thread without hanging the computer, but if you then click on any entry found - hang.

There is a related issue, which I think I have now resolved.  If the entry in the "Reply to" field in the yymmdda.log file does not exist, that is a later entry (not earlier, as above), elog will cause a duplicate entry, always in bold, with entry no 0 to appear in the listings.  This entry is an artifact that appears in the listings, not a real entry in a yymmdda.log file.  Again, finding the rogue entry is the tricky bit.

When one has "Allow HTML = 1" to permit HTML in attribute values, is it only a subset of HTML that is rendered?

I find that <br> and <a href="..."> tags are properly rendered, for example, but lists with <ol> and <ul> are not.

• As you can see...
• <UL> is possible

Isn't that list in the message text rather than as an attribute value?
