Hi,
I'm using squid's SMP functionality to distribute requests to many
squid instances and distribute workload to multiple processors.
However while running squid's workers after a while worker processes
crash with the error below and coordinator does not start them again:
...
FATAL: Ipc::Mem::Segment::open failed to
shm_open(/squid-cf__metadata.shm): (2) No such file or directory
Squid Cache (Version 3.5.20): Terminated abnormally.
...
Does a solution exists for this problem? (permissions are OK in /dev/shm)
When everything is OK coordinator listens to http_ports/https_port and
distributes connections to workers(at least that's the conclusion I
got from looking access.logs).
[root@squidbox ~]# netstat -nlp|grep squid
tcp 0 0 0.0.0.0:8080 0.0.0.0:*

7887/(squid-coord-1

7895/(squid-3)
Also is my way of using SMP functionality correct, since I want to
distribute all connections between workers and to listen only specific
ports?
I have attached the squid.conf.
