GEMs: Too many open connections work-around

Phil Mann

Recommended Posts



We are currently seeing an error when attempting to connect to ems via GEMs - Too many open connections.

tibemsadmin reports:

Connections: 468

Sessions: 2084

max_connections = 0

In the past when we have seen this we have usually performed a full shutdown and restart of ems and bw, but I'm wondering whether there is any way to identify old, unused connections and destroy just those

please consider that maximum number of programmatic admin connections (i.e from EMSCA or applications using EMS Admin API) allowed in EMS server is 256. Connections from the tibemsadmin tool are unlimited.

You are maybe hitting this limit of 256.

Please use tibemsadmin to connect to EMS server and run "show connections full". The output will show which connection is programmatic admin connection under FSXT column. For example:


show connections full


tcp://localhost:7222> show connections full

L Version ID FSXT S Host IP address Port User ClientID Sess Prod Cons TmpT TmpQ Uncomm UncommSize Uptime

J 8.4.1 V3 454 ---A + EC2AMAZ-1LP0F97 [::1] 49789 admin 1 1 1 0 1 0 0.0 Kb 0:11:20

J 8.4.1 V3 455 ---T + EC2AMAZ-1LP0F97 [::1] 49804 admin 1 0 2 0 0 0 0.0 Kb 0:11:15

C 8.4.1 V3 456 ---A + EC2AMAZ-1LP0F97 [::1] 50699 admin 1 1 1 0 1 0 0.0 Kb 1.348



Hope this helps, regards
