I am using Debian 6 (Squeeze). The server has 4gb of memory in it, and 8gb of swap. I'm starting to get memory alloc errors at high application load times, but from top command:
Mem: 4055944k total, 3915436k used, 140508k free, 10444k buffers Swap: 7999480k total, 0k used, 7999480k free, 3604496k cached
The system isn't even trying to use the swap?
Why would this be happening? I would like to upgrade the primary memory, but this isn't possible just right now.
As requested, the error/exception is:
terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc ·
which as far as I know, is only ever raised when memory has run out.
Also, here is the output from 'free -m':
total used free shared buffers cached Mem: 3960 3334 625 0 19 2847 -/+ buffers/cache: 467 3493 Swap: 7811 0 7811
The system is not under heavy load right now though.
