Re: idle in transaction process

Hi

 

Yes , restarting the slon resolves the issue. But. there are other processes also in my application  which connect to postgres . Those processes can also cause "idle in transaction" postgres connection . So, I was wondering if I can make use of tcp_keepalives_idle , tcp_keepalives_interval and tcp_keepalives_count configurations in postgresql.conf to get rid of this "idle in transaction" process after a certain amount of time . Will this help or not ??

 

 

 

Thanks...

Hi All

 

I am using postgres-8.4.0 on a cluster setup with slony-2.0.4 being used for replication.

Recently , I saw a "idle in transaction" postgres process as below.

 

postgres 13052 14742 0 May13 ? 00:00:00 postgres: slon abc 172.16.1.1(49017) idle in transaction

I wonder what could have lead to that hung postgres process . I googled about it a lot and they say that it could be 

because of abrupt netwotk issue between slony and postgres . But in my case slon was connected

to its local postgres database. So, network wont be an issue in this case . What else could be the reason for

this hung process ? What should I do to come over this kind of issue in future. I think this hung process would have

taken locks on various tables. I wonder if killing the "idle in transaction" process would cause the locks on the tables

to be released or not. Can anyone please  help me on that.

 

Of course it is a slon process if it is not due to a network issue, then might be any of your scripts, if not you can try by restarting the slon process on origin.

Abbas.

 

Thanks in Advance .
