Hi Shaun, Looking at your log watch (attached file), I don't think disk space is the issue. You still have 28G of free space which is quite a lot. I would first start looking in you log files for clues. Take a look at /var/log/messages file. If you have a specified time when you noticed the node hang, look around for that time. When linux hangs, it can be caused by a memory issue, hardware issue, or kernel issue. Hopefully the log file will give you some clues. Here are some commands that you can used to look for large files and why your system is using so much disk space. This will list the disk usage of a directory and list the top offenders: *du -skh * | sort -k1 -n -r | head * * * I would check /var, first... for example: * cd /var* * du -skh * | sort -k1 -n -r | head* Here is the output example: *[root@AllStar var]# du -skh * | sort -k1 -n -r | head* *220K spool* *188K run* *40M lib* *40K lock* *37M cache* *28K db* *24K empty* *20K yp* *12K account* *8.0K tmp* I normally start at the root level and work down... cd / du -skh * | sort -k1 -n -r | head *[root@AllStar /]# du -skh * | sort -k1 -n -r | head* *146M lib* *124M root* *124K dev* *101M etc* *88K tmp* *87M opt* *78M var* *34M sbin* *16K lost+found* *12M boot* This will find large files > 10M in size and help you find the large files. * find / -size +10M -exec ls -latr {} \;* As far as files to delete, I would start in */var/log*, there are log files that could be large. If log rotation is working, it would be self limiting, the fact that you are up in to 100G+ disk space, I am not sure what is eating the disk usage. I find the /var is the usual problem area for disk issues. Let me know what you find out and I will be glad to let you know what files you can remove and what files you should not delete.

My AllStar node just hangs every so often. I have to physically drive up to the remote high-site and pull the power to get it working again. I don't know much about fault finding in Linux so could someone give me a pointer.
I attached the last bit of text from this email "You have new mail in /var/spool/mail/root" .
I suspect that the hard drive is running out of space but why? And what files can I delete to give me more HDD space?
