High Memory Utilization on WAE Standby Central Manager

[Sentillatiben Velaytham]

Hi Guys

Need to help / suggestion on this one. We have 1 primary Central Manager and 2 Standby Central Manager. No issues since deployment ( 2 years ) . Lately ( since 1 month ago ) , the 1 of the stanby central manager's memory is being over utilized by multiple java processes. It goes up to around 85% and stays there until it is rebooted. After reboot , memory utilization returns to normal but slowy builds up again until we hit the 85 - 90% before going for another round of reboot.

Checked for bugs but could not find any. Software version is 4.2.1. Since its a standby central manager , I find it weird that the memory is being overutilized. I have read in this same CISCO forum that monitoring memory utilization for WAE is not really a good way to determine performance , but this is the Stanby Central Manager. Does the statement above apply to the Central Managers as well.

Correct.

WAAS, both the accelerators and the CM are based on Unix platforms. These tend to use all the memory they can get, even on standby devices.

A better thing to monitor is the swap file size, load average or the cpu time spend waiting for IO. 'top' will give this output.
