FATAL: The database system is in recovery mode

From

Hi,

I have got a problem with PostgreSQL 7.3.2 with cygwin under Windows 98. At
our clients sometimes during normal work the database goes into recovery
mode. I do not know what couses it, but it seems that this happens when one
of the client applications freeze (or the client application freeze when
this error occurs?). We got the same application and database under NT and
Windows2000 and those work without problem. As I know the database could go
into recovery mode only at startup time, am I right?

Does anybody know what can be the problem and how can I solve?

Thanks,
    Attila

I'd highly recommend against using postgresql with cygwin in production,
and further, very highly recommend against using it under win9x, due to
the stability issues on that platform.  Can you just put it on a Win2K or
better a linux box and let the clients all connect to that machine?

More than likely, when the client app crashes, it's causing a kill -9 to
be send the the backend, which is causing a the database to restart or
something along those lines.

I would second this. We actually explicitly limit connections to 50 with
Mammoth PostgreSQL for Win32.
Also win9x just doesn't have the preemptiveness needed in the kernel to
handle something like PostgreSQL.

PostgreSQL on Win32 for WinNT/2000/XP is fairly stable though, as long
as you leave it at 50 connections
or less.
