You could certainly encounter this too when the machine's load shoots to the |
6 |
roof or one of the running programs is vehemently leaking memory. |

When trying to log in via ssh, wait for a few minutes for the prompt |

or response to |

come up. Most of the time it takes a while for the kernel to kill the |

misbehaving |

process. |

BTW just in case its a load issue, this patch to kernel/fork.c could help |

I would have speculated this being a probable issue with one of the |
49 |
hardened-patches applied to the kernel but seeing redhat with linux |
50 |
2.4 there hmmm |

Are they by any chance all running the same programs/services? |
