Using PHP 5.2.2RC2-dev (cli) (built: Apr 13 2007 04:03:02) on Windows with

for %x in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do
start php -r "ini_set('error_log','/tmp/test.log');for($i=0;$i<1000;$i++)error_log(str_repeat('%x',5000));"`;

And then doing some analysis of the log file I'm finding that not all
the data has been written.

Array
(
    [A] => 4965993
    [B] => 4590918
    [C] => 4525905
    [D] => 4695939
    [E] => 4495899
    [F] => 4710942
    [G] => 4495899
    [H] => 4645929
    [I] => 4540908
    [J] => 4580916
    [K] => 4535907
    [L] => 4470894
    [M] => 4480896
    [N] => 4550910
    [O] => 4610922
    [P] => 4500900
    [Q] => 4630926
    [R] => 4480896
    [S] => 4500900
    [T] => 4535907
    [U] => 4630926
    [V] => 4470894
    [W] => 4645929
    [X] => 4825965
    [Y] => 4845969
    [Z] => 4920984
)
Lines (Should be 26 * 1000) : 23973
Longest (Should be 5024) : 5024
Shortest (Should be 5024) : 5024

Out of the 26,000 lines expected we are missing 2027 lines.

So no corruption of the lines, just missing ones.

The only explanation I can think of is that the locking is working,
but nothing is waiting for the lock to become available.

Richard.
