Zinc Server and Backlog Situation

I think, that a not called ZincServer can be the reason for a backlog
problem - I have several Zinc server running in various gems and one of
them is not called - and the backlog number for that task is increasing
without end - as I understand this instance can be a reason for a not
working garbage collection.

That also means, that the low-level receiving part of Zinc should be
rewritten for a regular timeout - and then after that timeout an abort
should be executed ?

This analysis seems to me to be exactly right.

Marten,

How are you calling the ZincServer ... if you are using one of the
startup scripts provided with GLASS, you will see the following pattern:

System transactionMode: #manualBegin.

Exception
   installStaticException:
     [:ex :cat :num :args |
       "Run the abort in a lowPriority process, since we must acquire the
        transactionMutex."
       [
         GRPlatform current transactionMutex
           critical: [
             GRPlatform current doAbortTransaction ].
         System enableSignaledAbortError.
       ] forkAt: Processor lowestPriority.
     ]
   category: GemStoneError
   number: 6009
   subtype: nil.
System enableSignaledAbortError.
"This thread is needed to handle the SigAbort exception, when the primary
  thread is blocked on an accept. Assuming default 60 second
  STN_GEM_ABORT_TIMEOUT, wake up at 30 second intervals."
[
   [ true ] whileTrue: [ (Delay forSeconds: 30) wait ].
] forkAt: Processor lowestPriority.


and this code is intended to avoid a CR backlog in a gem that is idle
and waiting on a socket ....
