Created the directory and put in the cache dir as you specified, still got an error FATAL: Ipc::Mem::Segment::create failed to ftruncate(/squid-squid-page-pool.shm): (22) Invalid argument.

It's not squid fault, the server Os has to be configured to provide enough shared memory to squid. Most of the time, it's enough to mount tmpfs mounted as /dev/shm, but I'm not familiar with SuSE installation defaults. > cache_dir aufs /ssd/squid/cache0 45000 64 1024 > cache_dir aufs /ssd/squid/cache1 45000 64 1024 This won't work in smp mode. Each worker needs a dedicated cache_dir, except for rock store. But your squid never reached that point. The way you did all workers will try to use both cache_dirs. I guess you want one for each worker. So replace those two lines by: cache_dir aufs /ssd/squid/cache${process_number} 45000 64 1024 That way each worker will use only it's own, exclusive, cache dir. > workers 2 Ok, you are trying to use 2 workers.
