We have had logging running for about a week now with no apparent problems,
but yesterday I routed all our traffic into varnish, and now bad things
/var/log/varnish/varnish.log just stops growing after a while and a tail -n 1
gives me pages after pages of:
Pipe Shut write(read)Pipe Shut read(read)Pipe Shut write(read)Pipe Shut
read(read)Pipe Shut write(read)Pipe Shut read(read)Pipe Shut write(read)Pipe
Over 4 megs of it just now actualy.
/etc/init.d/varnishlog status reports "varnishlog (pid 11936) running".
I thought it took a fairly long while at first, but now it happens quckly,
whithin 5 mins.
On a possibly related note, varnishncsa segfaults when trying to process this
log. both as
cat /var/log/varnish/varnish.log | varnishncsa -b -r /dev/stdin and
varnishncsa -c -r /var/log/varnish/varnish.log
Log size ~1G
varnishlog -c -r /var/log/varnish/varnish.log seems to work fine
Truncating and starting over does not seem to help on the first problem, but
varnishncsa seems to be more comfortable with a smaller log.
What to do?
