Hi,
I need to run a number of PostgreSQL servers in different FreeBSD jails.
I managed to run a first instance of PostgreSQL server in a jail, but
after I launch a new server in another jail the first one starts to
return an error messages like the following:
semctl(1507328, 4, SETVAL, 0) failed: Invalid argument
The problem in general is: only one instance of PostgreSQL server processes clients' connections, all of the others return semctl errors.
I had this exact same problem. I never found a solution. The cause appears to be that, since shared memory is not segregated between jails, the newly launched Postgres instances corrupt the shared memory of previously running Postgres instances.
I'm running 9 jails on a server right now, each with their own instance:
....
and never noticed any issues ... but, this is with 4.11, not 5.x, so maybe something has changed?
Can you tell please what version of PostgreSQL are you running?
