Hi Tom I installed CentOS 4.4 final late last year. The kernel version was the latest about a year back. I have been running yum updates and applying patches regularly. Can you give me any ideas on how to troubleshoot (and establish that this issue is due to a kernel bug) the kernel packet drops? I am beginning to think it is a firewall related issue. But I have been unable to replicate the issue!
I have been monitoring the firewall logs (could not find much there). Maybe I will also sifting through the messages log on the servers. Will post if I find anything!

Thanks for any help extended! "Connection refused" means it was refused at the kernel level; if the postmaster had rejected the connection the message would be different. So you need to be looking for OS-level issues. Given that you seem to be running a rather hoary kernel (2.6.9 is a ways back no?), maybe an update there is indicated. Firewall problems are a possibility too. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
