Hi Andrei, First, I inform you that I may not contact for the following period: From November 1st to November 19th
Second, I noticed my misunderstanding in previous mail. > > Nevertheless, it is necessary to take into account that the option > > TCP_USER_TIMEOUT is supported by Linux kernel starting since 2.6.37. > > In a lower kernel version these changes will not take affect. > Does it mean how do we support Linux OS whose kernel version is less than > 2.6.37? I understand that you pointed out my implementation. I'll remake patch files when I return. Finally, I write test method for each parameters here roughly. You may use iptables command on linux when testing TCP_USER_TIMEOUT. You may use pg_sleep(seconds) command in postgres. I'll write the details after my returning. Continue to discuss the socket_timeout, please. Best regards, --------------------- Ryohei Nagaura
