A disk space problem when using nginx 0.6.32 and apache2

[baalchina]

Hi, everyone.

I am using an nginx 0.6.32 and apache2 in a CentOS 4.4 server, running
a php web forum. Apache listening in 127.0.0.1:81, and nginx proxy php
requests to apache.

I made my /usr/local 10g space. But I found the space is decreasing.

for example:


[root at bbs ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda5             10317828   2161500   7632212  23% /
/dev/sda1               101086     11318     84549  12% /boot
/dev/sda7            541552520 268074680 245968540  53% /data
none                   2076724         0   2076724   0% /dev/shm
/dev/sda2             10317860   9781764     11976 100% /usr/local
/dev/sda3             10317860    210432   9583308   3% /var
[root at bbs ~]#


after 10 seconds


[root at bbs ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda5             10317828   2161500   7632212  23% /
/dev/sda1               101086     11318     84549  12% /boot
/dev/sda7            541552520 268075128 245968092  53% /data
none                   2076724         0   2076724   0% /dev/shm
/dev/sda2             10317860   9781888     11852 100% /usr/local
/dev/sda3             10317860    210432   9583308   3% /var


Look at the available space of /usr/local.

And after a while, available space of /usr/local is 0, my forum begin
has some problem, for example, can not upload images.

It is strange that, when I using du command:

#du -ch /usr/local

219M    /usr/local/
219M    total

All file size in my /usr/local is 219M。



Somebody told me to restart apache and nginx, I did, and then df , I
found that....

/dev/sda2             10317860    262264   9531476   3% /usr/local

So, my space had come back.

BTW, I changed my apache and nginx temp and logs directories to
another directory rather than /usr/local. so I think it's not the logs
or temp cause this problem.

BTW2, I am using https in a little site, can https cause this problem?

Thanks a lot.
