Maybe it is because of connection timeout.  The logfile records
data-connection trials with your hosts like follows:

10/27 21:29:14.36 [16081] 2263+0: FTP-LOCAL: connecting to client's PORT 192,84,230,XX,208,251

...

Since the timeout (5 seconds) seems enough to wait response from
your host XY (==Linux?), a probable reason is that your host XX
(== Solaris?) is set not to get incomming TCP connections.
