Is your /usr partition full? Or almost full? That could be a problem. Here’s a way to fix it.
Run:
cd /usr/local/apache/logs/
List the contents of that directory with ll. Are there any big files? Empty those files. Here’s an example. If you want to empty error_log for example, just run:
echo > error_log
You can repeat this procedure in /usr/local/cpanel/logs/. Just empty any large files.
Then go to /usr/local/apache/domlogs/. And list the biggest 10 or 20 files. For the top 10, run:
ls -al -SR | head -10 —>
Are there any big files? Running awstats for that domain should clear the file. Just run:
/scripts/runweblogs user
Login to WHM. Check if log rotation is active for apache and cpanel logs. For apache, click Service Configuration -> Apache Configuration -> Log Rotation. For cpanel, click Service Configuration -> cPanel Log Rotation Configuration.
