Tonight, my long-time friend died. He was living in the basement for years, always reliable, always at my service, keeping my files, watching for my git repos, being my private cloud, and so many things more.
He wrote his last syslog entry at 0:21 a.m., passed away and never woke up.
I found him cold and motionless this afternoon, but could not do anything. Any attempt of reanimation failed.
Goodbye, little BananaPi, fare thee well, and if for ever.
I promise you, your legacy on SD card will live on with a new board.1 -
Ever since i was a little boy, i was fascinated by the stars in the sky and what made them shine. I used to wonder how our universe came in to being. What made it what it is today. What will happen to it long after we re gone. Will it die? Will it live forever? How big is it? Why is it big if it s big and why is it small if it s small. "God did it" was never a satisfying answer for me. God does not play dice as Albert Einstein said. So many questions went through my 10 12 year old mind. Until someone recommended to me the book, "A brief history of time". The book answered a lot of my questions and gave birth to more. Computer science is like my crush. I love it as a friend. But Astrophysics, its the true love of my life. It not only quenches my thirst, but it satisfies my curiosity, while making me more curious. Its an endless cycle. It teaches us that we came from the stars, we go back in the dirt, and only to be returned to the stars again.
Stephen Hawking, his work, his books, taught me so much. Inspired me. Made me more curious. And today the world has truly lost, one of its greatest people.
You will be missed Sir Hawking. RIP. -
Bullshittery continues. This time around, absolutely innocent, clamav is root cause. For once not incompetent idiot, but piece of software. IDK if that makes me happy or upset.
So our email server that I configured and took care of died. RIP. Damn, better put it back together ASAP. So Im under pressure, while still pissed at everything that I ranted before (actually my last 2 rants were throttled, and in total all of that happened past 60 minutes but devrant rate limiting) I start auditing logs. You imagine, we kindda need it NOW, and it's second time last month clamav is pulling stunts and MTA refuses (properly) to work without antivirus. So pressurized, I look at logs, what the fuck went wrong.
clamav deamonize() failed - cannot allocate memory
Hmm. Intresting, but sounds like bullshit. I know server is quite micro becouse they wanted to save on costs as much as possible, but it has well over half a gig free ram just before it crashes (like 800MB) with that message. Is it allocating almost gig in one call or what? Looked carefully at trusty htop while it was starting, and indeed, suddenly it just dies with quite a bit of ram free, almost as much as it weights already. And I remember booting it up when I was configuring it, and it had fair bit of headroom.
Google, help me friend... Okay, great, so apparently at some point clamav loads virus DB into ram (dafuq?), and than forks, which causes spike of 2x the ram usage, and than immidietely frees it up.
Great, that sounds like great design decision... At least I know, I can just slap on SWAP file, restart it and call it a day.
It worked, swap file is almost empty (used 15megs, 900 megs free ram, whatever).
That leaves me wandering, who figured out to load DB to ram? That means pretty much that clamav will eat a little bit more ram each vir db update, and that milisecond "double ram" spike will confuse innocent people who just wanted to run clamav and it worked last *long period of time* and now crashes without warning without any changes to configuration.
Maybe there is logical explanation, I want to know it.8
