Hi all,

Today one of our client got these messages in the firebird.log:

DBSERVER (Server) Wed Apr 23 09:07:15 2014
Access violation.
The code attempted to access a virtual
address without privilege to do so.
This exception will cause the Firebird server
to terminate abnormally.


DBSERVER (Server) Wed Apr 23 09:07:15 2014
Shutting down the server with 146 active connection(s) to 5 database(s), 1721 active service(s)

DBSERVER (Server) Wed Apr 23 09:07:21 2014
XNET error: XNET server initialization failed. Probably another instance of server is already running.
operating system directive CreateMutex failed
Cannot create a file when that file already exists. 


DBSERVER (Client) Wed Apr 23 09:07:21 2014
Guardian starting: "C:\Program Files\Firebird\Firebird_2_5\bin\fbserver.exe"

Before these, several (I mean a lot) "INET/inet_error: read errno = 10054" was logged and the Server refused to answer to the requests for a few minutes.

What does the "1721 active service(s)" clause means? How can I find out the cause of the crash? How can I avoid it? I've searched the tracker to no avail, couldn't find any record that can be applied. 

Server version: WI-V2.5.2.26540 Firebird 2.5
Server implementation: Firebird/x86-64/Windows NT
SuperServer

VmWare Virtual Windows Server 2008 R2 Standard, 16 GB RAM,8 core CPU. 

Any hint is greatly appreciated.

Best Regards

Zsolt
