Apache Problems

[Darkedge]

I am using cpanel 6.0 on a freebsd 4.5 install. I have downloaded the latest buildapache.sea and installed it using both the raise hard limit option and also the raise fd_setsize limit to 16836. It seems to be instlaling properly however I am still receiving messages like this in the error log

[Tue Feb 25 22:01:28 2003] [warn] [csd] filedescriptor (1030) larger than FD_SETSIZE (1024) found, you probably need to rebuild
Apache with a larger FD_SETSIZE

If anyone can think of anything that could help this please let me know. My monitoring system keeps sending incomplete packet errors and then apache seems to restart.

I have also rebuilt with 'raise hard server limit' and 'raise fd_setsize limit to 16836' but still the errors show up, and perl deliveres blank pages after a while.



This is on RH 7.2 though.

Same here

Same here

Somebody know why the error say "larger than FD_SETSIZE (1024) found" after rebuild apache with "'raise fd_setsize limit to 16836" ????

Any ideas ?

( Cpanel 6.0.0-S88 RedHat 7.3 )

Just had this aswell on one fairly busy server after the cpanel upgrade (v6 stable) and easyapache recompile.

Is there any way to check the current FD_SETSIZE?

Also getting this on a RH 7.2 box. Have to reset apache twice yesterday and twice today because non of our sites were responding. No problem prior to build 6.

Well after looking aroudn the system I found this

/usr/local/etc/rc.d/init.d/filelimits

looks liek its designed to prevent this problem. Also looks like it onyl runs on linux. Perhaps it will fix the problem for you guys unfortunately I run freebsd/

I have found this :

If you are hosting large numbers of virtual servers or have a particularly
rich skel these values may have to be increased. This can be done by adding
the following lines in your /etc/rc.d/rc.sysinit immediately after the /proc
filesystem has been mounted:


echo 256000 >/proc/sys/fs/file-max
echo 32768 >/proc/sys/fs/dquot-max
echo 2048 >/proc/sys/fs/super-max
echo 67108864 >/proc/sys/kernel/shmmax
echo 384 >/proc/sys/kernel/shmmni

------------

etc/rc.d/init.d/filelimits change /proc/sys/fs/file-max to 131072 and /proc/sys/fs/dquot-max to 16384

but ... It works ?

I have file-max --> 131072
I don´t have /proc/sys/fs/dquot-max

hrm

will that work for freebsd as well or only linux

Well i dont have any of these FD Size problems but i found and fixed the problem i beleive. If i didnt i fixed one of them . You guys can download the new buildapache.sea from me here

http://www.ndchost.com/cp/buildapache.sea

give it a shot. let me know what happens

note: i have ran this my self and it looks like it worked but no way for me to test really.


Quick Install/Run notes...

rm -rf /home/cpapachebuild
mkdir /home/cpapachebuild
cd /home/cpapachebuild
wget http://www.ndchost.com/cp/buildapache.sea
sh buildapache.sea
/etc/init.d/apache stop;/etc/init.d/apache start

Hello

I was facing the same trouble on my server which is running on linux. There was a solution worked out for the same, as this is a generic, i think it should work on freebsd as well.

Here we go

Download the buildapache.sea.

After you configure what modules you want to compile with it, you can let it install expat and watch it until it untars apache and creates the Makefile.

That's the tricky part. then type ctrl+z to stop that process. cd to the apache src tree in buildapache/.

Edit the os/tpf/os.h file and double the FD_SETSIZE.
then type fg to go back to the build process and let it compile and install.

This solved the probs on my server for the FD_SETSIZE probs. Hope it works for you as well.

regards,

Anand

I am sorry i forgot to mention, the credit for this solution goes to Darren from burst. He was a real help to solve this probs on my server.

anand,

the FD Limit Size patch does more than that from what it looks like.

Recompiled using your buildapache.sea earlier today and had someone watching the error_log since. Everything seems great now and I think the problems are fixed.

Thank you for sharing... much appreciation

Darkedge,

It should.

anand,

Sorry it was late last night, i wasnt trying to be a dick if thats the way it came off. I'm just stating that by looking at the patch it's doing more than just editing that file, by the looks of it, it doesnt even use that os.h file.


My point was you shouild try my buildapache.sea since the patch that cpanel was using by default is in it.
