URGENT : StreamServerPort: bind() failed: Cannot assign requested address

Hi, I've an application running on RedHat Linux and we are using Postgres as our DB. Initially the DB was running perfectly butdue to some requirement we stopped the DB with " pg_ctl stop -m 'fast' " command. When I tried to restart the DB/Postmaster it says: StreamServerPort: bind() failed: Cannot assign requested address Is another postmaster already running on port 5432? If not, wait a few seconds and retry. cannot create INET stream port Since I don't have root access , I took the help of the Sysadmin to reboot the system and the DB server(POSTGRES) startedcorrectly , but when I stopped the DB server with above mentioned command and started again it throws back the same old error. Is thereanyway to get rid of these. I found some details in archieves at http://list.linux-vserver.org/archive/vserver/msg04095.html . But I don't understandwhat to do next. The O/P of >netstat -plunt | grep 5432 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 0.0.0.0:54320 0.0.0.0:* LISTEN - udp 0 0 0.0.0.0:54321 0.0.0.0:* - And O/P of netstat -ranv Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.83.103.0 0.0.0.0 255.255.255.192 U 0 0 0 eth2 64.102.29.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 64.102.29.1 0.0.0.0 UG 0 0 0 eth0 Any pointers/help in resolving this issue will be highly appreciated.

Hi, I believe a fast shutdown prevents new connections to the db, sends termination signals to any applications with current connections, and then after it receives confirmation that those applications have aborted their transactions and closed their connections the db stops. It sounds like your application is either not responding to or confirming the shutdown request from the db. The details in that archive were trying to explain how to find which process / application are still connected to the db after the fast shutdown attempted to terminate them. Without root access though maybe you aren't able to see which process is still attached to the db? Try doing a ps -A and see if the postmaster is still showing up in the process list. If it is then you know for sure that the db is not truly shutdown.

Many TCP stacks have a timeout before they will let a pre-existing port number be reassigned. (This is to prevent any risk of packets for old connections getting delivered to the new owner of the port.) regards, tom lane

If the old postmaster were still alive, he'd be getting a different error message --- the data directory lockfile is checked before trying to grab the port. regards, tom lane

Hi Mike, Thanx for the response. The ps -A don't have POSTMASTER and I did check it earlier too. Do you foresee any issue with Linux configuration or is it the POSTGRES issue? Please let me know how to proceed from here. Thanx in advance.

Hi Tom, Thanx for the reply and suggestion. Actually , I did wait for more than 5 hrs before posting this issue in this alias. Itwill be really great if you can advise on how to proceed from here. Does the below information points to any issue with my LinuxBox configuration is it an issue with POSTGRES: The O/P of >netstat -plunt | grep 5432 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 0.0.0.0:54320 0.0.0.0:* LISTEN - udp 0 0 0.0.0.0:54321 0.0.0.0:* - And O/P of netstat -ranv Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.83.103.0 0.0.0.0 255.255.255.192 U 0 0 0 eth2 64.102.29.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 64.102.29.1 0.0.0.0 UG 0 0 0 eth0 Thanx in advance.

No, it shouldn't, because that is associated with the creation of the Unix socket file, which happens after creation of the TCP socket. Given that you're seeing a kernel error on attempt to create the TCP socket, I'm convinced that you're wasting your time thinking about Postgres-internal conditions.

Hi Tom, I don't understand what you meant by "This is a kernel-level issue and you need to be inquiring ..." .

Also you can run a simple perl/python/ruby/java script (like this http://myclass.missouri.edu/~atb6x2/NETSERV/NS_serverpl.html) to (try to) open a socket listener on 5432 and have it just sit there. If you do that the output from strace would be shorter than trying to start up pg and you might get an idea where the socket problem is.
Hi Rob, I did run the script from http://myclass.missouri.edu/~atb6x2/NETSERV/NS_serverpl.html and it didn't give any error and theO/P of netstat -plunta | grep 5432 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 0.0.0.0:54320 0.0.0.0:* LISTEN - tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 9481/perl udp 0 0 0.0.0.0:54321 0.0.0.0:* - But I don't understand why I cant bind to the same port thru POSTGRES.

Looks like it could be an IP address issues: bind(3, {sa_family=AF_INET, sin_port=htons(5432), sin_addr=inet_addr("64.102.22.156")}, 16) = -1 EADDRNOTAVAIL (Cannot assign requested address) write(2, "LOG: StreamServerPort: bind() f"..., 163) = 163 write(2, "/apps/systran/postgresql/bin/pos"..., 41) = 41 write(2, "cannot create INET stream port", 30) = 30 write(2, "\n", 1) = 1 unlink("/apps/systran/postgresql/data-linux/postmaster.pid") = 0 exit_group(1) = ? Process 9912 detached try just having the tcp socket run on 127.0.0.1 starters and see if you get the same msg... What does your ifconfig -a look like?
