Server not responding randomly - urgent help needed

Postby Kicksome » 02 Dec 2007, 13:16

I'm not sure to go with this, but it's driving me crazy.

The SFS just randomly stops responding to all requests. I have a port monitor setup but it still responds when this happens so I have no way of knowing about it until I wake up to 20 messages from upset people.

I have two different zones and both of them just stop working. These zones use totally different code. I added the second zone for some unrelated things and both just stop working. I have the wrapper set to 1 gig of memory. And it seems to make no difference.

I've tried this on two different physical servers. I can understand why one zone would lock up - due to code. But two totally different zones locking up at the same time? SFS keeps responding to requests - it just does nothing with them.

I just looked at the log closely and tracked it down to this: Once this happens - everything on that SFS instance goes to hell. Any ideas???

I've looked at the other logs - and the it has always stopped responding to new requests after this error:

although it keeps processing old requests but once that users disconnects they can't connect to the server again - no matter what zone.

Is there a way to monitor this so at least I know when it happens? At least then I can reset it. Right now it's a massive problem.

Hi,
according to Java documentation:
"Socket operation on non-socket.
An operation was attempted on something that is not a socket. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid.

Can you give us more details about the OS and SFS version that you are using?
Are there other errors in the logs?

I'm using Windows 2003 Server with SP2 with 4 gigs memory and 2 dual core amds. I've switched servers about 3 different times and I've always got this error (Windows 2003 servers - some intel chips). I just assumed it was my code that was locking up until I just recently realized that all other zones were locking up too - but the SFS was still up - just not doing anything. I wish it would at least crash so it would restart - or stop responding to requests so port monitoring would work and I would know it was down.

I'm using Sun jre1.6.0_03 - although I've gone through other version of Sun JVM's.

There are no more errors in the log - just this exact error:

Smartfox version is 1.5.9 although this has happened with earlier versions.

I *might* be wrong about all the zones not responding to requests - it might just lock the one zone, at least in this one case I found. I noticed in this instance when it happened the other zone was still working okay.
