[jcifs] "The network name cannot be found" after 30 seconds

Well, it appears that I should have tested the 1.2.25a fix with a larger
file. When I'm using JCIFS to transfer a file of non-trivial length, I get
this after the reconnection that happens after 30 seconds of inactivity:

java.lang.RuntimeException: zero termination not found

jcifs.util.transport.TransportException: Transport1 timedout waiting for
response to SmbComSessionSetupAndX

Here's the last part of the log file, is there something earlier I should be
looking for?
