SocketException during network play

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start network game across computers
2. play for ~5 minutes
3. NullPointerException from server, SocketException on trace.

i'm trying to playtest with my girlfriend across our laptops and we're
getting a SocketException on the server after a ~5 minutes. 
NullPointerException dialog comes up and then the server closes.

Exception in thread "main" java.net.SocketException: Connection reset

John - need more info:

1.  It's happening consistently, right?
2.  What was the exact setup - 2 machines (1 w/client&server, 1 w/other 
client), or
3?  Any firewalls/routers involved?

Also, do you by any chance have the NullPointer stacktrace as well?

hey-- good questions.

* the problem happened all 3 times we tried playing.
* we have a router in our apartment.
* i hosted the server and client on my laptop and opened port 3444 on my 
firewall.
* she connected with the client (no firewall changes for her)
* (both machines running win xp)
* everything would connect fine and we would play for a while (~5 minutes)
* NullPointerException from server (but no trace that i could find)
* SocketException trace in the eclipse console that i pasted above.

i don't think it's a router/firewall issue since we connected at all.  (i'm 
trying to
remember, but i think it maybe have happened the 3 times after someone executed 
a
turn, but damned if i can be sure if that's true or what moves were performed 
before
the crash.)

edit: i (want to think, but really not sure) that the errors happened after the
*simulation* of the turn, not just after clicking done, if that wasn't clear.

Which JDK versions(s)?  1.5 or 1.6?  This bug in 1.5 could be related to it:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5076772
http://quickserver.org/forum/viewtopic.php?t=512

I haven't been able to reproduce it running 2 clients + server all on one 
machine.

sorry, i meant to add that.  we're both using 1.6.  (in fact, something to note 
in
general, blobs jar doesn't run with 1.5)

Yeah, noticed that with the JAR as well.

Does this really happen after 5 mins every time? If so, I'm leaning toward 
blaming
QuickServer.

yeah, could very well be with QuickServer, although i'll admit i wasn't 
watching the
time that closely-- 5 mins is more of an approximation, so it could be 
something with
the combination of game moves we were doing. *shrug*

it appears to be related to exploding an exploding blob.  i haven't figured out 
the
consistency.

20+ minutes of automated play (no explosions), and no crash so far.  I'll try to
script in explosions.  Can someone else try to reproduce this?

I played a couple of network games including a few explosions and didn't see 
this.

Cannot reproduce, therefore closing.  Reopen if it happens again.
