After Updating And Compiling tlds.txt File MTA Had Tcp_smtp_server At Almost 200% CPU Utilization
Last updated on DECEMBER 20, 2017
Applies to:Oracle Communications Messaging Server - Version 7.0.5 and later
Information in this document applies to any platform.
The tlds.txt file did not contain the latest domain information, to it was updated. Consequently, the TLD_HASH_SIZE had to be increased.
The changes were compiled but after doing so, it was noticed that the MTA had tcp_smtp_server process at almost 200% CPU utilization.
The following KM documents were referenced for the above steps:
Is There an Easy Way to Update the internet.rules File? New tlds.txt (Doc ID 1664115.1)
Unknown Host Or Domain When Sending Outbound Emails To Any Email Address Under a Specific Top Level Domain (Doc ID 1622031.1)
Is it possible that the cause of the spike in CPU utilization was because of the above steps taken? It seemed very coincidental time-wise.
Is there a way of "safely" making this change?
Updated the tlds.txt file and compiled it into the Messaging Server configuration.
