Hello! We are running 8.4.13 on this particular database and recently we have been getting empty two phase commit state files inside the pg_twophase directory. These prepared transactions can't be rolled back due to the empty state file. Here is an example of the error message.
ERROR: two-phase state file for transaction 121421120 is corrupt The only way to get rid of this is to restart the database, which is just a bandaid solution at this point. Have you guys seen this before? I have googled for this but can't seem to find a single instance of this happening to anyone. I sure will work with our developers to see where in our code is generating this file and go from there. But in the mean time, do you guys have any idea on how I should pursuit this on the database side of things? Here is a little more info about one of the empty file. It does look like the file was created empty. -bash-3.2$ stat 073CBD40 File: `073CBD40' Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: 830h/2096d Inode: 100663469 Links: 1 Access: (0600/-rw-------) Uid: ( 499/postgres) Gid: ( 402/ dba) Access: 2013-07-12 23:05:48.369557197 -0700 Modify: 2013-07-12 23:05:48.398557197 -0700 Change: 2013-07-12 23:05:48.398557197 -0700 Any help is appreciated and I'd be more than happy to provide more info.
