[Spce-user] Memory Utilization very high since yesterday mr5.5.2

[Alex Lutay]

Hi,

Is you system publicly accessible? Maybe you have been scanned or
received some (D)DOS attack? It is hard to say something from here.

Check the log files size to see the abnormal size to know the type of
the load SIP/WEB/... you need to understand who uses all right now RAM.
Restart this component to free the used RAM.

Sure, report here your findings.

Maybe someone dumped you DB massively?
A lot of SELECTS can happens if someone was scanning you with a lot of
REGISTER/INVITE SIP messages, which forces kamailio to perform selects, etc.

I suppose mysql/ngcp-panel restart should clean memory usage.
You should perform this during off-peak only.

It depends on the service.
