Hey guys,
I do a high load test, the test keep one hour. One hour later , varnish
works fine with restarting child process some times but don't write log
file. It don't write anything in _.vsl file after a period of time , even
these keep alive words 'Rd ping ...' ,'Wr 0 200 PONG...' . Prior to this,
it wrote about 16 M . What's wrong ?
I don't know how to get gdb information , so Not 'Include a backtrace of
the core-dump' ,sorry
The test case detail:
servers:
10.217.12.67 A siege (a opensource software), used to simulate
with the http requests
10.217.12.19 varnish server
10.210.128.199 apache server , the backend of varnish with flv files
command( run in 10.217.12.67):
siege -c 100 -i -l -f test2.url
test2.url content :
