NVR5232-EL crash during playback

[michele5353]

ok he just did it again. Here is the result: playback from the web gui does not work, and smartpss and dmss are inaccessible.
However, I noticed that the problem corresponds to a Google Chrome crash, I try edge...

 

[michele5353]

unfortunately no solution. I set all the cams to h264h as suggested but the problem always recurs.

1. Did You try latest version of SmartPSS Lite (no old SmartPSS)?
Best: configured from zero (different user login or computer)...

2. is this SmartPSS was configured to connect to NVR by local IP address or serial number (P2P)?

 

[michele5353]

I'm trying normal smartpss, not lite. But in any case the problem often occurs even when using only the web gui.
Ps: no p2p, only local IP

 

[michele5353]

First I carried out about 20 minutes of testing playing from smartpss and at the same time also from dmss (assuming it was the NVR that was unable to support the two things), but the problem did not arise.
Just now though, I opened the playback section in smartpss, selected an ivs event and it immediately crashed.
I can't understand anything anymore!

if this is not a windows problem (You can block NVR by accessing web interface from many different Windows/Macs) and network problem then the only logical solution is simply report failure and return the NVR for repair/replacement with a new one.

The only clue I found is in the log.
At 23.13 I started the playbacl and it crashed. The problem was resolved at 23:29 when it says stop playback. It's as if it were actually stuck in playback.

 

[steve1225]

this can be thermal problem (heatsink not glued to the processor), which will create problem at higher use (playback etc for a few minutes)...

but the log shows no errors. Furthermore, the fan doesn't even increase in speed.
I also checked the bandwidth during playback, and I'd say that's not the problem!

 

[michele5353]

For general information:
even the thermal problem excluded. During playback this is the result

@steve1225 is way smarter than I am on this stuff, but I continue to believe the bottleneck is being created by another device or your own PC reaching some limit of buffering and locking up

 

[bigredfish]

Not sure about that memory though…

If you wanted to rule out bandwidth, memory, or overtaxed hardware( or corrupted firmware), why not just turn off all recording of the live cameras, restart the NVR so its not recording.( that will free up memory and bandwidth) then try to remote in either with smartpss or direct from the web gui. Try viewing or downloading video remotely, If it still crashes then I would agree with The Big fish on some kind of network issue. If that turns out to be the case, Bring a laptop to the site and try it again direct or with a switch and try to access it again, see what happens, I have a feeling you have corrupted or mis configured firmware that is doing this. If it still crashes on a local lan, then you might have to wipe it out and start from scratch, we all know how unreliable dahua firmware is.

EDIT---> I would start at the NVR first on a local lan and work backwards, in this case it hard to say what end of the equation is the issue. Isolation with a laptop and the NVR is a good place to start.

Interesting older thread about the same model , but no definitive resolution.

NV5232 less stable than NV4116?

For years, I ran a hodgepodge of 14 mixed brand ONVIF cams on an Amcrest NV4116 with the only Dahua firmware version that preserved motion detection on all the cams. Several months ago, I swapped it out for an Amcrest NV5232 and updated that with again… the only Dahua firmware version that...

Just for curiosity, what is the time you have set for the NVR to block the login for a bad password attempt?

security- account lockout section -30 times, lock for 5 minutes

I ask because I had a version of both SmartPSS and iDMSS some years back that would go crazy sending login requests to the NVR and finally max it out and the NVR treated it like failed login attempts. had to wait or reboot

I did some tests assuming it's smartpss. Unfortunately the problem also occurs with smartpss lite version.
I updated the firmware, with the latest one available on the empiretech website.
I also tried viewing the CPU and memory usage data during playback, and as you can see from the photo attached above I don't notice any problems.
the remaining bandwidth is also more than sufficient.
I even did the test you said:
I connected with a laptop directly on the switch where the NVR is connected: always the same problem.

 

[michele5353]

this is my config

I think such a problem comes up in the log.
my log is clean, no errors

there is one more thing, which You can do before sending this NVR back to repair...

Default NVR to factory settings...
Then do startup wizard (password, network, date etc) and add all cameras at once.. You will need to format drives one more time...

Do nothing more in NVR configuration (no AI changes, no storage settings, no network/security etc settings).

Check how stable NVR works for live view in web view and SmartPSS...

If this will work, then it means that source is in some strange NVR settings You did in past but we don't known which one.
Second possibility: HDD/database/config structure were corrupted and this created problems..

After that You can do other settings, but checking after each one is NVR stable..

If this will not work, then simply send NVR to repair to seller.
