memory handling: should memory ever go down?

[mattlandis]

I'm curious how memory should work with snom ONE.

Should snom ONE be using more memory with a heavy load during the day then release memory when there is no load over night?

 

Or does memory use only go up?

No, memory does not go down. The way the memory allocation works in the PBX is that is does perform a garbage collection, but never returns memory to the OS. This is because of the real-time nature of the PBX and the requirement that it should run "forever" (or the next software update). Otherwise, you'll sooner or later up with memory fragmentation, that's where on the paper the process owns only relatively small amount of memory, but the OS cannot allocate new any more.

thanks for clarification.

 

we had an issue with cpu usage ramping up and killing snom ONE (which appears to have been Grandstream gateways...when we removed them it stopped ?)

 

reason for watching memory closer than normal.
