Newley setup Feed the Beast server (Direwolf20 1_5) Crashes?

[SuperSjoemy]

Hello people!
First of all i want to note that i'm new to the forums here sooo, hooray!

Anyway, i have recently setup a 24/7 feed the beast server running the Direwolf20 1_5 modpack.
It ran smoothly for about a week or so, then i heard people complaining about wierd lagg spikes etc.
Like a day or 2 later the server began crashing at random times and i had to reboot it. I have already looked on google and stuff but was in-successful of finding a solution.

The error report is as follows:
[SEVERE] Encountered an unexpected exception ReportedException

[SEVERE] We were unable to save this crash report to disk.

Of course i have no idea what this means..
I would like to get a solution asap and thank everyone on the forum in advance!

I'm currently keeping the server off because i'm afraid the world could get corrupt or something

Greetings, SuperSjoemy!
P.S. If my english is a bit incorrect or has other grammatical issues, i'm dutch and i don't consider my english 'that' good

[SEVERE] We were unable to save this crash report to disk.

This means the disk you have stuff save to is full or has little space so you need to empty it partially.

Thanks for the quick response, however; in the computer it says that there is at least 25 gigabytes of free space?

Try just deleting a couple unnecessary things like old backups that you no longer need and stuff to see if it will make JAVA recognize there is space on the disk.

That or he maxed out on allocated ram so it could not generate the crash report to save as it has nowhere to load it.
