William Sobel commented on OLIO-38:
-----------------------------------
Please give me some more information:
OpenSolaris version?
Load Level (how many concurrent users)?
I will also try to load the the evented machine gem in isolation and see if I
can reproduce the same problem.

> Key: OLIO-38
> URL: https://issues.apache.org/jira/browse/OLIO-38
> Project: Olio
> Issue Type: Bug
> Components: rails-app
> Environment: OpenSolaris 2008.11
> Reporter: Mandy Waite
>
> Rails app crashes after a random period of time when running on Thin on
> OpenSolaris. Error output by Thin is:
> Assertion failed: nbytes > 0, file ed.cpp, line 622
> Abort (core dumped)
> Which indicates that the problem occurred within native code in the
> eventmachine gem.
> The assertion checks that there are bytes available to be written on a call
> to eventmachine's Write(). At the time of the crash OutboundPages.size() = 0
> OutboundPages is the deque used to queue pages of data for writing.
> Stack trace:
