<BR>
We’re run varnish 2.1.5 for some week now and we still do not understand some behavior regarding the shared memory activity.<BR>
We specified a –sfile,/var/lib/varnish/varnish_storage.bin,50G in the configuration but it’s impossible to go higher than 25G used by varnish. Please see the following cacti graph:<BR>

<BR>
<BR>
In addition I can see varnish doesn’t seem to be able to handle more than 1 million objects:<BR>

<BR>
When the child process get killed, the load of the system was very high:<BR>
Apr 20 21:46:44 server-01-39 varnishd[21087]: Child (5372) not responding to CLI, killing it.<BR>
....<BR>
Apr 20 21:49:57 server-01-39 nrpe[18101]: Command completed with return code 2 and output: CRITICAL -<B> load average: 159.00, 159.32, 77.02</B>|load1=159.000;15.000;30.000;0; load5=159.320;10.000;25.000;0; load15=77.020;5.000;20.000;0;<BR>
....<BR>
Apr 20 21:48:43 server-01-39 varnishd[21087]: Child (5372) not responding to CLI, killing it.<BR>
<BR>
All this makes me believe we have an issue with some kernel parameters that do not allow varnish to handle as many objects as we configured it.<BR>
<BR>
Would anybody have an advice for this problem ?<BR>
