[Quickfixj-users] File Lock on FileStore impossible to free

[Graham M. <gm...@ma...>]

Nick,

We have seen this problem, too.  Thanks for tracking it down. (FWIW,
we were running 1.0.3 not the HEAD).  One thing to note is that I
think this manifests itself more egregiously on Windows than on *nix,
because of Windows' more aggressive file locking...
