Woah - simmer down cowboy.

To be fair René, as I said, I did search this list, and I did see your email from back around 2006, but "restart it a few times" isn't much of a solution. Additionlly, I wasn't sure if we had the same problem since you reported syslog-ng using 100% of your CPU, and mine only seems to need 50%, and I only have one, single core CPU. I suppose I could have been more clear about seeing your "solution" but I didn't think it was necessary. I apologize. In fact, I actually thought about emailing you or Corinna directly about this, but I didn't know if that was proper list etiquette.

I have debugged a few other problems recently for various cygwin services--their problems all seemed to be related to which different environment variables are set whether you log in on the windows console and then run the cygwin application vs. when one logs into cygwin via ssh. Matters are also complicated when dealing with all the different windows 2000 permission models.

If I find a solution to this syslog-ng problem I'll let the list know.


thank you,
Grav
