Description:
Bug ID 1209409: Address lists with thousands of addresses can cause MCPD to become unresponsive and use 100% CPU ... Symptoms ... If there are thousands of addresses in an address list, validation of the addresses can take extended time. ... While MCPD is validating the addresses it will use nearly 100% of the CPU. ... Also, during this time, other daemon might timeout their connection with MCPD and/or restart. ... - Longer load /sys configuration time including on upgrade. - Longer configuration sync time, where full configuration sync is more prone to cause this issue. - Modifications using the webUI consume longer time and might timeout. ... Depending on how long MCPD spends validating the addresses, other daemons, including TMM, might timeout their connection to MCPD and/or restart. ... Fix Information ... The time it takes mcpd to validate an addresses list that contains nested address lists is greatly reduced. ... Behavior Change
