Re: [Quickfix-developers] MS VC++ release builds

[Antonio C. <ant...@ga...>]

Dear Tim,

We are experiencing the same problems described in your email dated June
14/2004.

We are using MS VC++ 6 SP5 with default compilation and link options and
QuickFix 1.7.1. The target application is being run under Windows Server
2000 SP4.

In most cases we detected memory errors on incoming messages: we often get
the error "Message nn rejected: CompID problem" even if the FIX message
logged in our log file via the QuickFix log function shows correct tags and
values. It may happen that we have such a problem once or twice in a day
under heavy traffic conditions, mostly on incoming messages. In few cases
this possible memory problem also caused outgoing messages to be truncated.

At times (not always) this problem is followed by an application crash: we
do not get any application fault window since the application simply
disappears from the Task Manager.

I have seen Oren's suggestion about the callstack. Did that help you solve
your problem ? We might try and use QuickFix 1.8.0, but the release notes do
not seem to address this problem.

Any help will be greatly appreciated

Bye,
