3CXManagementConsole.exe issue

[Elvin.H]

Hi all!

We had an issue: 3CXManagementConsole.exe on 3cx server begins to consume high CPU and Memory (CPU - 20-40%, RAM - over 2-4 GB). Then web management console stops working normally and softphones can't register. However calls are working by manually typing the number. Reinstalling 3cx, installing on another server, reloads are not fixing the issue.

We have over 1000 extensions and 60 groups. Also we have another 3cx instance connected to this by bridge. PBX version - 16.0.2.9
Upgraded to version 16.0.3.525 (alpha), but the issue remains. Then 3-4 hours later the issue fixed by itself. Can't understand why.. maybe because most users have logged off.

Anyone faced the same?

Need more info on your setup - https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

How much memory does the server have ?
Have you tried to increase the memory ?

Hi Elvin

Upgraded to version 16.0.3.525 (alpha), but the issue remains

not enough memory can cause trouble as you explain, but for sure alpha version is not for production use.

3CX version when issue begun - 16.0.2.910, now - 16.0.3.525
OS - Windows Server 2016 Standard
Server has 16 Gb memory.
Server hosted locally, on VMWare
Registration problem was with all softphones (Windows, android, IOS)

No we didn't try to increase memory.

Hi Elvin

I does'n seems to be a memory issue, as even with high consumption, 50-60% of memory always was free.
We upgraded to the next version as hoped that this issue may be fixed on it.


We didn't try increasing memory because once we had exactly the same issue and it did not help.
Now the problem has gone, but we're afraid that it may repeat at any moment.

16 GB on windows for 1000 extensions, 60 RG how many SC do you have?

Your server is dedicated to 3CX ? no scheduled task running ? no antivirus on 3Cx folders?

Is it possible having some windows update running underground in same time, so it can increase cpu and Ram use ?

" 60 RG how many SC do you have?" didn't understand that part.

This server is used only for 3CX. On antivirus we didn't exclude any 3CX folder, but during troubleshooting we turned it off completely.
There are no special scheduled tasks on server and no updates were installed recently and during the issue.

When the problem begins, 3CXManagementConsole.exe begins to consume a lot of resources (usually it uses 1-10% CPU and 1GB RAM), but there is still enough free CPU and Memory, so the system is not running out of them. Seems like ManagementConsole service suffers for some reason.

Sorry if my phrases are not so good; i'm french, just wanted to say you have a big PBX set 1000 extension is not common size, 60 RG, and asked how many simultaneous calls do you use?
because all this needs hardware ressources. So 16 Gb perhaps is not so much.

Prerequisite to 3CX install ask to remove antivirus scan on 3cx folders.

WU can DL files to update even if you don't apply right now.
Did you search in event viewer if something happens during time problem occured ? system events?

 

[Elvin.H]

We usually have 10-15 simultaneous calls. In https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/ it says that 16 Gb is enough for 1024 of sim calls (it's maximum in that list), but there is nothing said about extension number and needed resources:



In events there was nothing unusual at that time. We even installed 3CX on another server and restored from backup. The issue was still remaining on new server.

how many max SC can you use on SIP side and from 3CX Licence?

Do you use also IVR and Qs ?

From license we have 128 SCs, but they rarely go over 20.
We also have 9 IVRs and 5 Queues.
