I'm runing ejabberd-2.1-2 on

FreeBSD it05 8.0-RELEASE FreeBSD 8.0-RELEASE #0: Sat Nov 21 15:02:08 UTC 
2009 root at mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64

Suddenly, my /var partition is running out of space.

When I run df -h, i get:

]# df -h
Filesystem            Size    Used   Avail Capacity  Mounted on
/dev/mirror/gm0s1a    496M    373M     83M    82%    /

linprocfs             4.0K    4.0K      0B   100%    /usr/compat/linux/proc
When I cd to /var and run a du -hs I get:

# cd /var/
[root at it05 /var]# du -hs *
2.0K    account
2.0K    agentx
6.0K    at

4.0K    crash
6.0K    cron
168M    db
2.0K    empty
2.0K    games
2.0K    heimdal

2.0K    preserve
54K    run
2.0K    rwho
3.5M    spool
116K    tmp
24K    yp
So, it seems that something is sucking up all the space but doesn't have 
a file descriptor on the file system, so du is not finding the file.

Running lsof|grep /var I get:

So, it seems that ejabberd is sucking up 10Gb I'm missing on my 
filesystem, and that space is being reserved into the /var directory.

Is this a bug on ejabberd?

Is there any way to solve this without having to restart the server (not 
tried yet, as many people is using it....)

Thanks.

How
