Problems with 4 SIP servers hosted at OVH
Since September 16, we observe serious problems with our four servers in France (the IP addresses are at the end of this doc). The chart below shows max peak values of CPU measured for 12-hour intervals on our SIP servers. The max peak value increased seriously since 2008-09-16. The CPU load of SIP servers always increases when the server encounters network or DNS problems. The chart below shows the max of peak values for our 7 SIP servers during a period of two months. The max CPU increased due to our 4 SIP servers in France hosted with OVH.
For each max peak value of the above chart we have a detailed chart of a 12-hour period. For example, the max peak value of 52.13% measured in the second half of 2008-09-21, is taken from the chart shown below. It shows the complete detailed graph of the CPU loads of all our 7 SIP servers during the 12-hour interval in question. The values of CPU loads of four French servers (fr1, fr2, fr3, and fr4) increased dramatically two times during the observation period (connection was lost with two of them).
The detailed 12-hour charts are available for all points of the main chart. Refer to the full list of charts for a desired 12-hour period [CPU charts].
