Exactly same trouble with 9.4 (Specifically EDB 9.4.10-1 win32)

That's good to know, less because of 519b0757, more because of the latch
changes - but they also went in in 9.5...

Would it make sense to check some even older ones?

Could you use process monitor or such to see what the process is doing
while using a lot of CPU?

I'm not sure how to do this, especially considering that the process in question is running as a service?

Now, some more input:

* 9.5.2 server running on linux x86_64 - unaffected! (What a relief! We are moving to Centos soon anyway!)

* 9.4.4 server running on win7 32-bit - affected, same thing as on XP.


Thank you.

Nikolai

Andres
