varnish backing file gone missing

[Matt Schurenko]

I just noticed that the backing file I configured varnish to use is now gone:

[root at mvp13 ~]# ps -ef | grep varnishd
root      4419     1  0 Sep07 ?        00:00:00 /usr/local/sbin/varnishd -s file,/tmp/varnish-cache,48G -T 127.0.0.1:2000 -a 0.0.0.0:80 -t 604800 -f /usr/local/etc/varnish/default.vcl -p http_headers 384 -p connect_timeout 4.0

[root at mvp13 ~]# ls /tmp/varnish-cache
ls: /tmp/varnish-cache: No such file or directory

If I do an lsof I see this:

varnishd   4420 nobody    4u      REG                8,1 51539607552   62160904 /tmp/varnish-cache (deleted)

I'm pretty sure I never deleted it. Is this normal behaviour? What are the implications of this file being removed while varnish is running? Varnishd still appears to be working fine. I have another varnish server running but the backing file is still there. BTW I'm running varnish version 2.1.5.

Thanks,
