PostgreSQL running out of connections

Raising the connection limit hides whatever is holding PostgreSQL connections. How 2501 finds it, frees stuck sessions gently and leaves configuration and restarts to you.

PostgreSQL out of connections gets room back after 2501 finds what is holding them, clears the sessions that are clearly stuck and names the application behind the problem, leaving the connection limit to a person

SOLUTION_BRIEFING

// HOW 2501 HANDLES IT

When PostgreSQL runs out of connections, raising the limit is the tempting fix, but it changes the server's configuration, and an application that leaks connections soon fills the new limit too. 2501 finds what is holding the connections, frees stuck ones where you allow it, and leaves configuration and restarts to a person.

The cause is often an application or service account keeping connections it no longer uses, or a session left open mid-transaction, holding locks that other work waits behind.

What 2501 does

The PostgreSQL specialty takes the ticket from your ticketing system and investigates before it changes anything: which accounts and databases hold the connections, which sessions are idle or stuck mid-transaction, and whether one is blocking the others. Within your limits it clears sessions that are clearly stuck, and names the application or account behind the problem.

Raising the server's own connection limit is a configuration change, so it goes to a person with the evidence. Its report says what it changed and why. If PostgreSQL itself is down, it hands the ticket to the services specialty with its findings.

How 2501 handles PostgreSQL running out of connections: signal, find which accounts and sessions hold the connections, clear sessions that are clearly stuck within your rules, name the application behind it and leave raising the limit to a person

You stay in control

  • You choose the level: investigate only, act after a person confirms, or act on its own within your rules. The level is set per specialty, not per ticket.
  • Configuration and restarts stay with you: changes to server settings or to who may connect need approval, and it never restarts PostgreSQL.
  • Unclear causes go to a person: when the cause is unclear, it asks before changing anything.
  • Your rules apply: which clusters are in scope, the access you grant, and blacklisted commands that stay out of reach.

Frequently asked

Why not just raise the connection limit? A higher limit does not release what is holding the connections, so a leaking application fills it too, and the change waits for a person anyway.

Will it end sessions to free connections? Only sessions that are clearly stuck, such as one left open mid-transaction and holding locks, trying the gentlest option first.
