Обсуждение: could not create shared memory segment: Invalid argument
Hi, I have just installed the latest version of OS X panther (10.3.3) and am now getting the following error message: postgres$ /usr/local/pgsql/bin/postmaster -i -D /usr/local/pgsql/data FATAL: could not create shared memory segment: Invalid argument DETAIL: Failed system call was shmget(key=5432001, size=10444800, 03600). HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMMAX parameter. You can either reduce the request size or reconfigure the kernel with larger SHMMAX. To reduce the request size (currently 10444800 bytes), reduce PostgreSQL's shared_buffers parameter (currently 1000) and/or its max_connections parameter (currently 100). If the request size is already small, it's possible that it is less than your kernel's SHMMIN parameter, in which case raising the request size or reconfiguring SHMMIN is called for. The PostgreSQL documentation contains more information about shared memory configuration. Any ideas on how i can resolve this issue? many thanks in advance

Well, did you consider getting the value of SHMMAX? Check with ulimit (as the postgres user).

I'am also getting this same problem with 10.3.3 Server. Worked fine with 10.3.2. kern.sysv.shmmax: 4194304 kern.sysv.shmmin: 1 kern.sysv.shmmni: 32 kern.sysv.shmseg: 8 kern.sysv.shmall: 1024 Those are the Values i get from the command posted. Have you figured out a fix for this error?
