我正在运行带有mod_tile的Apache的地图图块服务器。
服务器每秒大约收到10个请求。
服务器在一天中的大部分时间都能正常工作，但是我会把这些随机服务器“冻结”。这些随机的5分钟冻结每天随机发生2-3次。看来Apache在这段时间内停止接受请求了？
See system load during a freeze。请参阅底部的“公共带宽”图表。在右侧，您可以看到出站流量下降了-这是冻结发生的时间。所有其他系统统计信息看起来都很正常。
5-10分钟后，冻结将“修复”。
以下是冻结期间access.log的摘要。冻结从14:01:18开始，系统在14:06:14恢复正常。

有人知道为什么Apache会随机冻结5-10分钟吗？
