If the problem goes away after rebooting, that would indicate a software
problem for me.
Do not reboot the machine, login at the console and find out what's wrong.
You should find out what software is running on the computer, kernel
version, pppd version (if you have pppd running).
Look at /var/log/messages, /var/log/syslog and the output of 'dmesg'
for warnings.
Run the software involved with debug flags turned on.
Run 'df -k' and see if important file systems are full.
Actually, it would probably be cheaper, faster and better to contract
somebody with Linux skills to troubleshoot this. No offence, but it's
almost as difficult to tackle a problem when you do not know the OS as
it is to remote diagnose it.
