It's not from strerror. The code prints this if CreateFiberEx returns null. It doesn't call GetLastError to find out why it failed, though.

According to the docs at
http://msdn.microsoft.com/en-us/library/ms682406(v=vs.85).aspx the number of fibers is only limited by available virtual memory so with a small enough stack size this shouldn't be a problem, or at least not any more of an issue than on Linux.

If memory serves, fiber is the Windows equivalent of a kernel task on Linux
systems. That message probably came from strerror. I don't know what one has
to do to get a message like that, though.

Any ideas on this? Charm++ doesn't report the original error message.

Dear NAMD users,

When I tried to perform the minimization step in my molecular dynamics
simulation, I received this error: CthCreate failed to create fiber.

It is possible to receive this error because I have not enough resources on
my
system?

Thank you in advance for any sugestions,

Simona Patriche
