GnuTLS internal error in Filezilla

Hi,

We have Apache FTP Server running in production for a while now, it's been
mostly rock solid, but we see the following issue pretty often in
production.

Response: 150 File status okay; about to open data connection.
Error: GnuTLS error -59: GnuTLS internal error.
Response: 425 Can't open data connection.
Error: File transfer failed

On the apache ftp server  logs, all we see is: 

INFO 2012-09-05 05:04:16,087 pool-3-thread-350 D- U- S-
org.apache.ftpserver.listener.nio.FtpLoggingFilter - SENT: 425 Can't open
data connection.^M

Could it be one of the following:

1. All passive ports exhausted

2. We have a slightly different configuration, where we start 2 listeners,
one with implicit SSL and one without. Both have the same passive port
range.

Thanks
Sachin
