We have a server that at least once a week will suffer from very sluggish performance. Memory will go into swap by about 10-15GB and the server has 36GB of RAM.
My question is can i find either when the server went into swap or what caused it to go into swap.
I have a feeling there is a single processes that is causing the issue but when i check the process list it all seems normal. The server is already into Swap at this point though.
