[Mapserver-users] Problems running Perl Mapscript under mod_perl

[Eric Bridger]

Sorry Mark,
But Jason's patches still have some problems.  We noticed exactly the same problems you
describe below.  We have been scratching our heads and hope to do some serious debugging on the
issue this week.  I guess it's good to know that the bug is reproducible.  Not some configuration
issue of ours.
