[SR-Users] kamcmd htable.reload propertiesHash problem

[Ginhoux, Patrick]

Hi Henning,

Thanks for your review.

As you said, that's strange behavior.

So I'm going to upgrade to 5.0.7, the time to set up a server. I'll keep you
posted asap.

Cordialement.

Hello Patrick,

this is strange. Normally if it can initialize correctly during startup,
then 
it also should be able to use the database later on. 

I did a quick check of the htable module in the repository. There have been
a 
few fixes related to rpc commands and also a bit related to the database in 
the last year. But I did not saw from the git logs anything like you 
described.

Nevertheless, you should try to setup the latest 5.0 release (5.0.7) - maybe

on a test system and see if the error is also happening there. There should
be 
no changes in database or configuration comparing to 5.0.1.

Best regards,

Henning
