Large file stops FTP working

I uploaded a large file over 1GB and it has stopped FTP uploading any new files across the entire server. I can change and upload existing files. There is plenty of space left for that particular owners virtual server. I did ulimit -a and the fsize is set to unlimited. This is running on CentOS 5. Any ideas as to why this is happening and how to rectify this?

core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 128362 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 128362 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited

Howdy,

Hmm, I hadn’t heard of that happening before. Do you see any errors or related messages in either /var/log/messages, or in any of the logs in /var/log/proftpd?

sftp-server[17993]: error: process_write: write failed

It writes an empty file. I found that if I change the group owner of the large file then ftp works. The ftp user was the same owner.
