Hello all!
I've been browsing this forum quite a lot lately. My server was crashing every now and then due to memory problems but with the help from many discussions, I managed to improve the performance of my win2003 server using mod_fcgid. I managed to save 400mb of RAM usage and it is all stable right now. 
Just one small little question, how do I disable the notices from mod_fcgid in the Apache error log? Is it even possible?
The error.log file grows about 3mb a day just because of these notices and I don't like these unnecessary logging. 
Edit: Nevermind, I think I found a line in the Apache manual which explains it:
| Quote: |
Note
When logging to a regular file messages of the level notice cannot be suppressed and thus are always logged. However, this doesn't apply when logging is done using syslog.

Well haven't found a fix. My error.log file grew to 3gb after a month. I am looking for a way to suppress these notices so I don't need to restart my Apache server every month just to clean the error.log file.
Anybody has any solution? Logging with syslog is not available for Windows server.
Edit:
Never mind. I always get a fix after I post questions. I can just delete the log without any problems. For some reason the last time I tried I was not able to delete the error log. Or perhaps it is the access log, maybe I got it mistaken.
Edit 2:
Looks like I am able to delete the log from my XP developer machine while Apache is running, then Apache simply recreates a new log.
However, on my production server, the log got deleted BUT when there are new entries into the log, the log is recreated with the same file-size as previous error log.
Furthermore, after the first delete, the error log can no longer be deleted again.
I am not sure if this is a glitch or what but I am a bit hesitant on restarting my webserver just to get rid of excessive logging data. |

mod_fcgid has a bug tracking system.
It might be a good idea to enter a new bug requesting that mod_fcgid log messages as 'Warn' or 'Info' as appropriate.
These messages can be suppressed using the LogLevel directive.
Traditionally, only one-time startup log messages use 'Notice'.
If you are comfortable building a module from source, you could download the source code and fix it yourself.
Search all the .c files and change every occurrence of APLOG_NOTICE to either APLOG_INFO or APLOG_WARNING, depending on whether you wish to see it in your log.
For example, in fcgid_proc_win.c you could change | Code: | ap_log_error(APLOG_MARK, APLOG_NOTICE, 0, procinfo->main_server,
"mod_fcgid: call %s with wrapper %s",
procinfo->cgipath, wrapperpath); |
to | Code: | ap_log_error(APLOG_MARK, APLOG_INFO, 0, procinfo->main_server,
"mod_fcgid: call %s with wrapper %s",
procinfo->cgipath, wrapperpath); |
Note that the warning level is just "Warn" in httpd.conf, but the name to use in the source code is APLOG_WARNING.
"Info" and "Notice" are what you would expect - APLOG_INFO and APLOG_NOTICE.

Thanks Steffen and tdonovan.
I have submitted the bug report and see if someone is up for it. Else I will have to learn to modify and compile the sources myself. I have no experience with these however.
@Steffen:
I see that you also uses mod_fcgid on this site. Would you mind if I ask how big does your error log gets and how do you handle it once it grow too large for your preference? |

I only get this two lines now and then in the log:
[Tue Jan 09 20:51:16 2007] [notice] mod_fcgid: call F:/web/al/forum/rss.php with wrapper d:/servers/apache/php/php-cgi.exe
[Tue Jan 09 20:51:16 2007] [notice] mod_fcgid: server F:/web/al/forum/rss.php(3208) started
My logs are auto emptied every day by my stats , which runs as a CRON once a day.

Those are the only lines that I get, except for Apache start-up/shutdown notices. I have quite a busy site and those 2 mod_fcgid lines are taking up GB's of space.
I added log rotation for the error log so I don't get one big locked file. Thanks for the help, I guess I'll have to live with this work-around.
