Message: 93903   

 

Hai,

    I am using 2009R1-RC1 distribution for my custom board.I am getting crash when I enter one particular folder in the USB stick. This folder contains around 743 files. I am getting this error consistently while I cant get the error for other USB sticks.  Can any one please clarify in this regard??

increase the stack of your application.  you are probably hitting a bug in uClibc that has already been fixed for 2010R1.
