Error in WebLogic Logs

Question

Hi all,
We have been seeing lot of error in the Web Logic Logs and we aren't able to figure out what exactly causing these errors..
I set the java Heap Size to 512 and also the file descriptor value to 4096. Even after this we are still getting these errors.
We are on PT 8.49 and HRMS 9.0 installed on LINUX machine with web logic 9.2

And also we are using DEV Web Profile in our Production Environment, does it make any difference?
And what is the DIfference between DEV and PROD Web Profiles??
Thanks,

I don't know why you get this error, but you could read some docs about this parameter :
http://e-docs.bea.com/wls/docs91/wlsmbeanref/core/index.html
Maybe due to some specific install and env, do you have Performance monitoring ?
What's the consequence for the frontend user ?
Is it also in dev environment ? Did you try to apply latest patch of WL9.2 ?
If you have no clue, then you may want to open a SR to the support.
Lastly, for DEV and PROD webprofile, that should not make any difference for your error, please see the link below for a short description :
