Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php NFS locking is not reliable, so file corruption is not entirely un- expected. Previous Comments: ------------------------------------------------------------------------ [2007-10-27 07:20:50] tom at razz dot com Description: ------------ i'm attempting to log php errors from multiple web servers (3) to a single nfs-mounted file: error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT display_errors = Off log_errors = On error_log = /mnt/logs/php/webprod-php-error.log lines are written in production to this file perhaps 1-3 every minute via error_log facility. there aren't logging collisions at the moment. nfs server is a netapp fas3020c. fstab line is: nyp-netapp-2:/vol/logs /mnt/logs nfs rw,bg,soft,rsize=32768,wsize=32768,vers=3 0 0 Thanks for the help! Reproduce code: --------------- <?php // run concurrently from multiple servers to see garbage appear while(1) { sleep(rand(1,5)); error_log("test error"); } Expected result: ---------------- an error log without garbage ^@ entries in between lines. interestingly, writing my own error_log which explicitly does: $lfp=fopen("/mnt/logs/logfile.txt","a"); fwrite($lfp,$log_message); fclose($lfp); does not result in the garbage data being inserted. Actual result: -------------- log contents look similar to this: [26-Oct-2007 23:57:20] /usr/local/www/web/common/php- include/facebook/class.Movi eLines.php : Using cached values [EMAIL
