The apache configuration file is messed up which created a restart for the process as indicated in the log. To fix this issue, you would need to re-update the same version of firmware currently operate on your unit. The process will be recreated based from your current database.
The root cause for the restarted of the apache is the configuration file messed up. Whatever in the apache.conf file made the process restarted, this could be the database component(s) or PKG application that is using the apache process-- something that are not automatically set correctly between process and application. I 've done in the past to fix this issue was (1) re-upgrade the same firmware version or (2) Upgrade to the newer version. Now, we have tried (1) but did not helped. Since Cisco is no longer in the Small Business for NAS, I would recommend you to upgrade to QNAP firmware. You can have much more software support in the community forums and other rich feature sets that QNAP maintain and added for each major FW release. Many of our NSS customers had done this route and found much more flexible to find the answers they need.
Follow are two options that I think is a path to fix your NSS issue.
1) Update NSS to use QNAP firmware:
a- Upgrade from Cisco firmware 1.5.0 => QNAP (Model: TS-459 Pro + (Plus)) FW 3.5.0
b- Upgrade from 3.5.0 to the latest 3.7.0 firmware
Note: Upgrade from 1.5.0 to QNAP 3.5.0 has been tested so this works for sure. I also tried to upgrade from 1.5.0=> 3.6.x. This also worked. QNAP just released FW 3.7.0, you can try upgrade direct from 1.5.0 => 3.7.0. The important for the upgrade is NSS must running 1.5.0 in order to upgrade to QNAP 's FW 3.5.x or higher.
2) If you know what to do with the apache.conf file, you can edit manually to make sure the file 's content are correctly written. Here is a link from QNAP and you may need to do some more research to understand before do this step.
Like you say, the community seems to be really powerfull.
I'm going to upgrade to QNAP because it'll maybe fix the html file problem.. Every config parameters are keep on QNAP ? Services like : web file manager are working with the same installed permission accounts ?
I'll do a feedback of my transition to QNAP later cause i'm not very confident with that.
Thanks you so much again for your help,
QNAP Firmware 3.5.0 has been installed with success and it fix the problem ! I'm waiting for updating to 3.7.1.
I am glad that worked out for you. For any firmware/software related issue, you can use QNAP forum for answer. For hardware/chassis, you have 5 years warranty from Cisco counted on the date you purchased. So you are in the win-win situation.
