Hello everybody,
our customer uses FMCv 7.0.5 and a Firepower 1120 running rel. 7.0.5.
The monitoring reported the following:
CRITICAL - mempool MEMPOOL_HEAPCACHE_0_1 usage is 94.41%, mempool DP System memory_1 usage is 53.29%
mempool Snort System memory_1 usage is 18.26%
mempool MEMPOOL_MSGLYR_HB_1 usage is 24.15%
mempool MEMPOOL_MSGLYR_1 usage is 24.63%
mempool MEMPOOL_DMA_1 usage is 61.54%
mempool MEMPOOL_GLOBAL_SHARED_1 usage is 24.64%
The FMC does not show any error or warning in the Health Monitor for the device.
The users does not complain about any issues.
I did no reboot of the device yet.
I went to the device and got the following output:

My questions:

Thanks a lot for every hint!
