O que pode fazer com que essas estatísticas do kernel (conforme relatado por top
) sejam tão altas?
Kernel: 152661 ctxsw, 2475 trap, 99065 intr, 1449 syscall, 3 fork, 2373 flt
Normalmente, meu sistema tem valores muito mais baixos, por exemplo,
Kernel: 487 ctxsw, 3 trap, 904 intr, 435 syscall, 3 flt
mas de vez em quando os números sobem e o SO congela. A carga é sempre < 1.
Obrigado!
