Hi all, I'm trying to configure Squid to run on machines with no writable permanent storage (just a ramdisk) and little memory. I've allocated a 4Mb ramdisk for the Squid cache. Ideally I would like to disable disk caching entirely and have Squid only use RAM, but I haven't figured out how to do that yet.
It has been working very well under light usage, however today Squid stopped working due to insufficient disk space on the ramdisk. When I investigated, I found that swap.state was using almost all the 4Mb space. The current swap configuration is: cache_mem 1 MB maximum_object_size 1024 KB cache_dir ufs /cache 2 4 16 (most other options are left at defaults). which I hoped would be enough to keep the cache small. Indeed, the cache dirs themselves don't get too big, but the size of swap.state is a real problem. Does this file normally grow without bounds, and if so, can it be avoided in any way? I would rather lose performance than risk having Squid crash, or being forced to restart it regularly. I found some articles which seem related: * Joe Cooper asked if it was possible to run without a swap.state file, and nobody replied directly as far as I can see: [http://www.squid-cache.org/mail-archive/squid-dev/200111/0057.html] * Dancer thinks that swap on tmpfs is not a good idea, but doesn't say why: [http://www.squid-cache.org/mail-archive/squid-users/199912/0455.html] Thanks in advance for your help, Cheers, Chris. -- _ __ __ _ / __/ / ,__(_)_ | Chris Wilson -- UNIX Firewall Lead Developer | / (_ ,\/ _/ /_ \ | NetServers.co.uk http://www.netservers.co.uk | \__/_/_/_//_/___/ | 21 Signet Court, Cambridge, UK. 01223 576516 |
