'cache_mem' does not show a valid value

[Tom Tom <tomtux007@xxxxxxxxx>]

Hi

Using Squid 3.2.6 with 4 workers:

I configured 'cache_mem 10240 MB'. Squidclient shows the output below:

$ squidclient mgr:config | grep cache_mem
cache_mem -2147483648 bytes


When I confiure 'cache_mem 20480 MB', then squidclient show this:

$ squidclient mgr:config | grep cache_mem
cache_mem 0 bytes


Does squid use cache_mem (so the output of squidclient is just wrong)
or does squid therefore does not use cache_mem?

Thanks a alot.
Tom
