Linux 3.10.0-1160.2.2.el7.x86_64 x86_64
OE 11.7.4 Enterprise
I have a Development server with 82 GB RAM and 21 GB swap.
There are two copies of Production - each with 7.5 GB of buffers -- and another 23 copies that are also copies but have very small buffer allocations (2 MB each).
Most of the small copies exist but brokers only get loaded occasionally -- only about 5 are running most of the time.
On rare occasions the kernel panics and kills-off the two "large" brokers -- because of a lack of memory. By "memory", of course, it means "virtual memory".
I asked my System Admin to bump-up swap -- preferably by about 10 GB.
He's not happy about it and suggests that I reduce the memory buffers.
I am not a System Admin and I don't profess to be any sort of expert about memory, but I don't see a problem. Adding another 10 GB of swap just means creating an extra swap partition on disc. Is there any downside to this?
Any thoughts??
