Re: IDS 4235 showing 98% memory usage, is it normal?

There is a 4.x known bug where the memory usage is incorrect.

The actual memory usage number can be determined from the service account by entering the following command:

bash-2.05a$ free

total used free shared buffers cached

Mem: 1934076 1424896 509180 0 18284 1214536

-/+ buffers/cache: 192076 1742000

Swap: 522072 0 522072

The "Mem:" row, "used" column is the amount of memory (in kilobytes) that

the "show version" command reports. However, this total includes the

"cached" amount.

So in the above example, the actual memory used is ( 1424896 - 1214536 ), or

210360 KB. This is ( 210360 / 1934076 * 100 ), or 10.9% of total memory.

Also, rebooting the sensor seems to clear up the erroneous memory usage reported by show ver.
