Re: Coprocessor responseTooSlow error messages
Ted,
There are no error message. Only a WARN. It lists all the arguments to the call. 
It seems like a resource configuration issue. I am unable to get past 60 concurrent clients or so.
And I did set the rpc handler count to 400.
(I just deleted the log file so I have to redo it again, it takes a while to reload my db as well)
 
Regards,
- kiru
