I will report back.
OK, I turned off flow control, rebooted, and ran for 48 hours with no problems. I then turned on flow control (the default), rebooted, and after 21 hours saw a failure, then two minutes later, another one. I think this proves my problems are related to flow control. How would you like to proceed? Is there a patch or change you would like me to test? Just close the ticket? I have a fix, but it is likely others would not know they had this problem unless they were monitoring their kernel logs or their network traffic for lag. -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.
