"Activity Monitor Job has encountered a problem" errors

[laredotornado]

Hi,

I'm using STS 2.6.0.SR1 on Mac 10.6.6. I am getting these errors periodically popping up ("Activity Monitor Job has encountered a problem") ...

There is no pattern to when these pop up, only that I always have to click OK to make them go away. Do you know how I can permanently make them go away? Thanks, - Dave

Hi!

Can you take a look at the Error log to see the details (and possibly a stack trace) of the exception behind this message? Posting the stack trace would be good to see where the real problem comes from.

Thanks!

Where is the error log located? - Dave

Open the view called "Error Log", there you should find some details for that error message.
Thanks!!!

Cheers,
