Spectrum is installed on a Linux system with 24 GB of memory. Top shows 23 GB of memory being used but does not show which process is using up all the memory.
Running "ps -aux --sort -rss | more" showed the top 3 processes using less than 9 GB of memory. Again, it does not show which process could be taking up all the memory.
Issue looks like cache memory is not getting released properly.
Release : 10.4
Component : Spectrum Core / SpectroSERVER
Run the following three commands to free up cached memory according to the reference link below:
sync; echo 1 > /proc/sys/vm/drop_caches
sync; echo 2 > /proc/sys/vm/drop_caches
sync; echo 3 > /proc/sys/vm/drop_caches
