log file cannot be locked with flock()

Hi,
I have a log file on my site which has to be updated by the script:
<?php
$fp = fopen($logfile, "ab");
if(flock($fp, LOCK_EX)){
fwrite($fp, $s);
flock($fp, LOCK_UN);
}
fclose($fp);
?>
It worked for 1.5 years without problems, but a few weeks ago only
incidentally a record is added. Most of the time the file cannot be locked.
My webhost provider uses php 4.4.7
However, my KISGB works great. And I saw that KISGB has a file addtogb.php
where flock() is also used and without problems to update $path_to_gb.
I would like to know the trick and how I can modify my script.
Thanks in advance and regards.
Hans

If the code "suddenly" stopped working and you have made no changes, then check what changes your host may have made. Also verify that the file permissions/ownership are the same as the KISGB file. That may answer your question right off Smile

Last week I informed my host about the problems. I only got a standard message from them that they received my complaint.
Permissions of dirs and files are the same as in KISGB. Also tryed 777 and 666.
I checked with phpinfo.php . It is a Linux syatem build jan 2008

Check the ownership of the 2 files to be sure they are the same, not only the permissions. If your host has taken a week and not gotten back with you then I'd be looking for a new host.

Use ftp client usually or have host verify.

Yes. The logfile you can't lock and the KISGB file you can lock.

It is not yet clear to me how to check ownership.
I use WS_FTP

Most good quality FTP clients (which I believe WS_FTP is one of them) have a way for you to change your remote view panel to show the "Owner/Group". If you cannot find this within WS_FTP, you can definitely do this using FileZilla (free from
