I dunno. I love to see how her mind flies away into her inner space when I talk about servers.

I see LSD25

Why no SELinux?

Huawei RH5885H V3 we’ve got 6 of them, each has roughly 6TB of RAM.
SAP used by local Telco, lots of fried DIMMs -
@netikras Physical machine is not low on RAM. Xen Hypervisor is limited to 6GB of RAM and it's running low on that. All other memory is free to be allocated to the guest machines.
Will surely share any findings. -
@netikras that's an physical server. I've tried to compare every possible xen hypervisor configuration with the lower version (VM Server 3.4.4) on PROD environment which does not experience this issue, and all of them seems to be the same. Well, I suppose will have to dig deeper into google. Once again, ačiū!
-
@netikras there are 449 processes, their RSS sums up to 436.421725MB and free shows 3050MB as used.
6047MB are allocated to xen hypervisor out of 261741MB and nothing in the hypervisor itself are using that memory, if that would've been regular linux box it wouldn't take so much time to identify what's wrong. I'll keep digging, unless you have any kind of insights.
Be to, ačiū! -
@pwar no, that's an oracle vm server 3.4.5
-
@con-fig I would use it if I would know what is leaking that :) furthermore, valgrind requires processes to be started using it as a wrapper as far as I recall.
Will try memleax -
@netikras made an typo, RSS is the column which is being sorted, however neither RSS neither VSZ does not show any increase in memory usage.
The only commands which shows shrinking free memory are free and vmstat and any other one. -
@franga2000 so you won’t upgrade php in prod by accident. That’s why
-
@ihatecomputers do you really hate computers? If yes, this method of yours is perfectly fine. Your machines will come back once you start loving them again.
-
Where’s NSFW tag?
-
@joykill yes, they are nice, though really time consuming when it comes to achieving the exact look you wish your dashboard had

ctrl+r you’ll skip half of those keyboard presses next time

@beegC0de by default rm is an alias for interactive shell mode, at least in most distributions.

How if I may ask
-
Can relate. Thank god I have my two dogs who are waked up by the first ones.

@Nhil my end has only that SQL machine and BSD router so it does not matter at the moment whether local communication works.
Though thank you for the responses I really felt frustrated that such cases happen in biggest Telco corporation in a country. And I had to spend whole day trying to explain them crazyness of this when I could've work with my Unix infra instead -
@Nhil yes, the other engineer thinks that I had an firewall blocking their requests until I showed him firewall logs.
Anyway, this won't work unless client accepts to move that one old SQL server to different subnet.
I just wish not to get such cases anymore..
Though I'm not sure what would happen if I routed just one machine to remote subnet /16.
They wish to test this setup replicated in different subnet on monday which most likely will work since The IPsec will route correctly -
@Nhil end point does not belong to me. AFAIK phase2 wont come up if routes were not there. Also 50.6 machine is able to ping other side(not all of it though). But I have no access there
-
You could just empty iptables ssve and reload them. On disable all zones via firewalld or ufw.
Great idea for bad customers! -
Splunk or graylog. Or syslog-ng
-
@gitpull noone merged your request! Glad you’ve enjoyed it

@HalfBloodPrince actually your brain becomes more responsive and it’s neuron activity increases while in meditation.
Brain activity != thoughts -
@lu1slpz only the ones targeted to beat insomnia :D

Are sysadmins in need of graphic cards? Only for mining crypto >:}
-
@linuxxx I see. I had similar alias fucking= “sudo apt”, which usually was used as fucking update; fucking install something :) then I switched to root
-
Why are you restarting apache?
-
@TheManDK oh man, now just make sure not to ignore your employees as your ex-boss did
