Logging / Event queue bug?

Postby shander » 06 Dec 2012, 16:08

Folks,

We're using an old (1.4.1p1) version of Poco, and would like to make minimal changes to fix the following bug,
assuming it is indeed a problem with Poco. We're asking for help to nail down exactly
what the problem is and exactly what we need to change to fix it.
The bug is intermittent, and so it's hard for us to debug or verify a fix.

Any help is appreciated. We're not that familiar with Poco internals, certainly,
and inherited most of our Poco code. As I've said we're not sure we want to upgrade
to a newer version -- we'd rather fix this specific problem, since the rest of the system
works ok.

Thanks in advance -- Steve

Here's what's on the stack when we experience this, as a segfault (on a unix system):

Steve,

It will be hard to help you without seeing the code. If it's proprietary and you can't post it in public, you can contact me OOB.
