[EP-tech] Re: IRStats and EPrints 3.3
I was investigating reports of "too many connections" errors from MySQL and trying to work out what was holding open all the available connections..

Hi,

I have found a bug with IRStats 1.x when used with EPrints 3.3.x

There is a memory cycle in the DatabaseInterface object which means that
those objects are never destroyed, and hence the object's database
connection is held open indefinitely (until it times out). If enough
IRStats requests are made in a short space of time this could use up all
the available MySQL connections.

This small patch fixes the issue:

Note this only applies to IRStats 1.x running under EPrints 3.3.x

Regards,

Tim


Thanks Tim!

How did you find it? It seems rather obscure :)
