Hi,
I have the same kind of error but what bugs me is that I cannot
reproduce this systematically. I am really wondering if this is a
permission PB on shm mount point and / or /var/run/squid permissions
:
some times the service starts normally ( worker kids stay up ) and
some times some or all of the the worker kids die with this error :
FATAL: Ipc::Mem::Segment::open failed to
shm_open(/squid-cache_mem.shm): (2) No such file or directory.
attached is the cache.log, and here below the squid.conf.
Best regards
