A TCP connection hangs occasionally.
TCP connections hangs, and data transfer cannot be completed.
-- The TCP connection is on the clientside. -- sys db tm.tcpsendrandomtimestamp is enabled (default is disabled). -- A virtual server's TCP's Verified Accept and Timestamps are both enabled.
You can use either of the following workarounds: -- Disable tm.tcpsendrandomtimestamp. -- Disable either the TCP's Verified Accept or Timestamps option.
This release provides improved interaction between TCP's Verified Accept and Timestamps options and the tm.tcpsendrandomtimestamp setting.
