Re^3: Fast provider feeding slow consumer

The error appears to occur due to the fact that the code uses "DBI" both as an ENUM and a module name. Try changing these 2 lines:

use enum qw[ IN DBI_ENUM ]; # *CHANGED*

my @Qs = map Thread::Queue->new(), 1 .. 2;  # set up two Qs
...
## start 10 walkers # *CHANGED* next line
my @walkers = map{ threads->create( \&walker, @Qs[ IN, DBI_ENUM ] ) } 
+1 .. $T; ##

This is not an optical illusion, it just looks like one.

Ditto for line # 70. Thank you NetWallah. `## process data produced by walkers while( $Qs[ DBI_ENUM ]->dequeue ) { ... }` [download]	[reply] [d/l]
