Database Connection
We are unable to connect to the database via SSH.
Your application is not running or in a unexpected state.

i have error 2026-03-18 08:15:56.455 UTC [51555] ERROR: could not resize shared memory segment "/PostgreSQL.243058984" to 16777216 bytes: No space left on device

The error "could not resize shared memory segment: No space left on device" is a PostgreSQL shared memory (SHM) limit issue, not a disk space issue. The default SHM size is 64MB. You can increase it by adding the RAILWAY_SHM_SIZE_BYTES variable to your PostgreSQL service's environment variables. For example, to set it to 500MB, use 524288000 as the value. See the PostgreSQL docs for more details.
