two questions: error_log and timeout

Hi all, I hope you can help me. I'm running php 4.3 as ISAPI under IIS on Windows 2000, SP3 MS-SQL Server 2000, SP2. I have these two problems that has been bugging me for some time: I'm logging php errors and warnings to a log file. But mostly there are no line breaks in the resulting file, which makes scanning the file very dificult. Is there a way to force line breaks in the error log? My second problem is a script that once in a while returns a time-out error, usually after having run for about 5 min. But not always. My standard timeout for php is set to 600 sec. And the script in question starts with set_time_limit(0); Any idea on how to pinpoint the problem? The exact error message i get is: CGI Timeout The specified CGI application exceeded the allowed time for processing. The server has deleted the process. This error, by the way, is not written to the error log. Tia Henrik Hornemann
