Re: [cobalt-security] RaQ3/4 + glibc Update (+ ChiliSoft) + MySQL = Problem

Hi David,

That's right. But many people have MySQL on their RaQs, which they either 
installed as unofficial and unsupported PKG, by compiling it from the sources 
or by installing the proper RPMs. 

MySQL (if utilized heavily) appears to contribute to the rapid memory decay 
in the affected servers.

Basically any application not limited to MySQL or where you got that one 
from. The underlying problem apparently has to do with the way how the 
operating system allocates and manages memory. So it revolves around either 
malloc() or the so called garbage collection.

MySQL just happens to make many calls to memory when it's utilized a lot, so 
it can accelerate the process which leads to ending up without usable free 
memory for new processes.
