Don't you have more details to share? There should be some hint here
as well, and usually you may be facing such things because of OS or
hardware problems.

If you are facing hardware problems, this may be a time to deploy a
backup and replay WAL up to where you wish to on clean disks.

9.0.4 has been released in 2011, so you are missing 4 years worth of
bug fixes, the latest minor version of the 9.0.X release being 9.0.19.
Note as well that 9.0 will be EOL at the end of the year, hence you
could do even better: an upgrade to a newer major version.
