Zimbra sudenly stoped sending and recieving email

[jwilliams@hometask.com]

Hi,

We are running zimbra 6.08. Everything had been running fine. This morning when I came to work no one can send or receive emails. This is a big problem. The message I am getting says "A network service error has occurred" and if I click show details I get a punch of stuff that it won't let me copy and paste here.

We are able to log in to the web interface and see emails. We just can't send or receive them.

Would be grateful for anyone that might be able to help me troubleshoot this. Let me know what information we need and I will do my best to get it.

Regards,

Justin

You need to look in the log files for the errors.

Which log file should I look in? I have a list of the files and where they are.

Thanks,

Is your server running out of HD space? Have a grep through your logs for "No space left on device" and I'd also check your space at the same time.

ok, I ran grep on mailbox.log and zimbra.log. No returns on mailbox.log, but on zimbra.log, the following:

Sep 24 15:40:03 mail postfix/postdrop[2718]: warning: uid=500: No space left on device
Sep 24 17:14:06 mail postfix/postdrop[24169]: warning: uid=500: No space left on device
Sep 24 17:16:07 mail postfix/postdrop[24570]: warning: uid=500: No space left on device

when i run "fd" on the system, here is the result:

Zimbra is running as a VM. I am new to this stuff. I have another data-store on my VM machine. Could I powerdown the system, increase the diskpace and then use gparted to resize the disk? Any advice would be greatly appreciated.
