HI , I Have a code that runs well , I use POP3

if (part.isMimeType("multipart/*"))
{


Multipart mp = (Multipart)part.getContent();


int n=mp.getCount();


}

BUT after a while I get the following :

java.lang.OutOfMemoryError
at java.io.ByteArrayOutputStream.write
(ByteArrayOutputStream.java, Compiled Code)
at com.sun.mail.pop3.Protocol.multilineCommand
(Protocol.java:295)
at com.sun.mail.pop3.Protocol.retr

(MimePartDataSource.java:61)
at javax.mail.internet.MimeMultipart.parse
(MimeMultipart.java:259)
at javax.mail.internet.MimeMultipart.getCount
(MimeMultipart.java:159)

please help -what is wrong ? what do I need to do ?
it is bug in pop3.jar in javaMail ?
in the mail server ?

thanks in advance - Sharona
