Error file descriptor

I have installed the gateway and with loglevel set to 0 , in the 
bearerbox.log
I see this type of errors :


2002-09-06 13:06:06 [2] ERROR: Error reading from fd 42:

and in the smsbox.log I see this type of errors :

2002-09-06 13:09:55 [3] DEBUG: HTTP: Resetting HTTPClient for `10.0.0.20'.
2002-09-06 13:10:55 [1] ERROR: Error reading from fd 23:

where is the error ? Is a problem with the file permission of 
 kannel..store file , or the kannel.access file ?

ps. Sorry for my terrible english #
