Hi,

So I have a few problems with my PostGreSQL and was hoping you could
help me out. one is I'm getting random timeouts and the errors I'm
seeing in the logs are

What version of Postgres and where did you get it?
OS and version?
Which logs?

On the 6/22/17 at 10:51am we had ERROR [08001] timeout expired at
System.Data.Odbc.OdbcConnection.HandleError(OdbcHandle hrHandle, RetCode
retcode)

A timeout expired, probably on client side.
Where are the clients relative to the server, local network or Internet?

2:23pm we had Error during indexfile unfixed fields readCurIndex:
6598CurFileNum: 551

4;25 pm Error during indexfile unfixed fields readCurIndex:
7054CurFileNum: 551

6/23/17 @ 5:57PM Error during indexfile unfixed fields readCurIndex:
4449CurFileNum: 552

Where are the above coming from as I can not find a reference to
readCurIndex in either the Postgres or psqodbc code?

6/24/17 9:43 am ERROR [08001] timeout expired
at System.Data.Odbc.OdbcConnection.HandleError(OdbcHandle hrHandle,

Another timeout.

di_central.di_web_records where starttime = '2017-06-26 01:07:34' AND

Looks like bad code in IsDuplicateSelect ID is triggering an exception
that shuts down the database.

Having an Issue of timing out or just randomly shutting down? other
errors I'm getting are duplicate key value violates unique constraint
"di_web_users_pkey"

I am not seeing that in what you show. In any case that is what a unique
constraint is supposed to do, throw an error when you try to create a
duplicate entry. The client/application code will need to be able to
deal with that.

Looks like some external process is shutting down the server.

I also have MySQL running on this PC and have an error in event viewer
we have a spam of errors Task category is WebHost and the source is
system.serviceModel 4.0.0.0 WebHost failed to process a request.
Sender Information:
System.ServiceModel.ServiceHostingEnvironment+HostingManager/45653674
Exception: System.ServiceModel.ServiceActivationException: The service
'/MySQLService.svc' cannot be activated due to an exception during
compilation. The exception message is: Memory gates checking failed
because the free memory (89677824 bytes) is less than 5% of total
memory. Process Name: w3wp Process ID: 10672

The only thing I understand in the above is:

"...the free memory (89677824 bytes) is less than 5% of total memory."

Whatever it is wants more memory.

if anyone can help me out with these errors that would be very much
appreciated.

Thank you

Thanks.

What version of Postgres and where did you get it? This Was from
postgresSQL 9.5

I'm not sure where this was downloaded from this was
installed on the server before I started with the company I work

for. my

guess is from the postgreSQL website

OS and version?
this is running a windows 7 embedded OS.

Do you have anti-virus software running on this machine?

Which logs?

From the PostgreSQL logs.

A timeout expired, probably on client side.
Where are the clients relative to the server, local network or Internet?
Local network

Where are the above coming from as I can not find a reference to
readCurIndex in either the Postgres or psqodbc code?

This is from a Log
called Trace and it comes from my Central Storage interface

What is Central Storage?

So the above is this third party instrument, correct?:

http://www.officer.com/company/10028921/dynamic-instruments

If so you might want to get in touch with them, as this looks to be
coming from their software.

Message: Exception during making connection to

UNICODE};Server=127.0.0.1;Port=5432;UID=postgres;PWD=root;Database=postgres;ERROR
[08001] timeout expired

That looks fairly straight forward the connection attempt timed out.

The question is why?

Do you see anything in the Postgres logs from this time period that
might help?

Do you have network issues that might prevent the device from connecting
in a timely fashion?

Is there any consistency to when these errors occur?
