Error message : couldn't send query: No error [php]

[Aurelien B.]

I have regularly a strange error with my local installation:
exception 'MongoCursorException' with message 'couldn't send query:
No error' in path/to/file/which/query

This is with PHP.

I use Windows 7 - 64 bits (both windows & mongo).
Currently with 2.0 rc 2, but I had also this bug with previous
version.

A first point to dive, I have this bug if :
- I shutdown the mongodb server (mongod),
- then I start this mongodb server (mongod)
- then refreshing the application page (not always).

I use persistent connection, there is maybe a link...

I was getting some intermittent "MongoCursorException" errors just as
you describe, however i recall it was a "broken pipe" message.

Nevertheless, i upgraded both MongoDB and the PHP Driver to the latest
versions and it went away.
However i'm running on Ubuntu Linux so it may be unrelated.

Try downgrading to a stable release and see if the bug persists.

If it persists then we know it is something other than the 2.0rc

Ok I didn't see that:

"but I had also this bug with previous

Are you using the Windows 7 driver and mongo? Or are you VMing it in Linux or something?

What language driver are you using?

[Aurelien B.]

Windows 7 and php driver for windows. ( = no VM).
I use mongodb php driver 1.1.4. Maybe this bug will go away with more
recent version but I didnt see that in recent changelog.

The driver got more aggressive about reconnecting in 1.2. If a
connection is dropped, it will still have to throw an exception
sometimes, but it will be more proactive about reconnecting.

[Aurelien B.]

Ok so I will go on 1.2 and come back if I find same bug.

[Aurelien B.]

Is the last version (1.2.4) working also with php 5.2.x ?
Because archive contain only php5.3 dll.
Did you stop dev for 5.2 ?

[Kristina Chodorow]

Ah, no, we stopped doing Windows builds Window builds for 5.2.

I am experiencing the same problem, but not all the time. Tried on 2.0.0-rc1 and 1.8.3, it's the same. I'm running the last 1.2.4 driver on ubuntu 11.04 server

Can you reproduce this? Can you write a script that causes this
error? Or can you narrow down what functions throw this for you?
