A Large Amount Of CLOSE_WAIT Sockets Are Building Up Causing The OBI 12c AdminServer To Hang (Doc ID 2706441.1)

Last updated on AUGUST 31, 2020

Applies to:

Business Intelligence Server Enterprise Edition - Version to [Release 12g]
Information in this document applies to any platform.


You encountered an issue where many (4000+) sockets build up in CLOSE_WAIT status (as identified by  'lsof' command) on port 9502.
When this occurs the AdminServer stops responding and has to be restarted. This may occur multiple times a day.
There is no resource (CPU/MEM) contention/utilization observed and operating system limits (ulimit) are configured appropriately.

Users are able to access and use Oracle Business Intelligence without issue.


 Exact changes on the system are undetermined.
