[CR #347826] If WebLogic reports “Too many files open,” this may indicate that you did not issue the unlimit descriptors command before you started the WebLogic server. This command increases the number of open file descriptors available, and prevents possible unpredictable behavior.
Workaround: Stop the WebLogic server using WebLogic’s recommended procedure, type unlimit descriptors at the command line, and then restart the WebLogic server.
