I use PostgreSQL 7.1.3 on both Linux 2.4 and Solaris 8 with my multi threaded application. The application has 16 threads and each thread opens a connection to PostgreSQL. Under Linux, this works just fine. Under Solaris, 11 threads succeeds in connecting to the database, but the rest fails with: connectDBStart() -- connect() failed: No such file or directory Is the postmaster running (with -i) at 'localhost' and accepting connections on TCP/IP port 5432? I am running postmaster with "-i -N32 -B64" so there should be enough allowed connections for my application. I have set the systems SHMMAX to 16MB instead of the default 1MB. Has anyone seen this happen before, or know why it could happen? The fact that 11 threads succeeds sounds very strange to me.
