Erlang runtime handle leak?

[Jan Jacobs]

  Hi,

I noticed an increase of handles been used by the runtime (erl).
Using handle.exe utility on the erl runtime I get the following:

Start:

Handle v3.42

Handle type summary:
   ALPC Port       : 4

   Directory       : 8
   EtwRegistration : 25
   Event           : 2075
   File            : 78
   IoCompletion    : 5
   Key             : 18
   KeyedEvent      : 2
   Mutant          : 2
   Process         : 15
   Semaphore       : 16
   Thread          : 1046
   Timer           : 6
   TpWorkerFactory : 16
   WindowStation   : 2
Total handles: 3342

Hour Later:

Handle v3.42

The Event handles increased by 77.
I am not sure if it is a result of me not closing socket/files correctly?
I do not know the internals of the VM, which actions in the code can 
cause this?

Platform and runtime:
Windows 2008 64Bit
R14A

Basic summary of application operation:
Read from socket and write to file. (No SSL)
Read from file and write to socket. (No SSL)
Web/SOAP operations with SSL.
ODBC Database interactions.
Running as a service.

Any help or suggestions will be appreciated.

Cheers
Jan
