Bug reference:      4601
Logged by:          V KUMAR

PostgreSQL version: 8.1.4
Operating system:   linux
Description:        Data saving and opening problem
Details:

we are experiencing the following error intermittenly in saving and opening
the data.

  While saving:

      Database error:     Error in saving the FMB MAP(Tippan). An I/O error
occured  while  sending to the backend.


  While opening:

             Database error: Error opening FMB Map of 2808060345. An I/O
error occured   while sending to the backend.


If we delete the record '2808060345', it shows error in another record and
goes on. The database was working perfectly earlier.

Does this error come from PostgreSQL, or rather from some application that
uses PostgreSQL? I ask because it isn't an error message I'm familiar with
(not that I'm an expert :). If it's from another application, we'll need so=
me
data directly from PostgreSQL (e.g. logs) to determine 1) whether the probl=
em
is really PostgreSQL's fault, and 2) if (1) is true, what to do about it.
