TNS-12518, TNS-12540, TNS-12615, TNS-12582, TNS-01159 and listener shuts down (only with Oracle 11.2 Database on Solaris 5.10 kernel version - 5.10 Generic_142910-17 i86pc i386 i86pc)

(Doc ID 2317731.1)

Last updated on OCTOBER 15, 2017

Applies to:

Oracle Net Services - Version 11.2.0.1 to 11.2.0.4 [Release 11.2]
Oracle Solaris on SPARC (64-bit)

Symptoms

a) You may start getting the following errors in the Listener log when making connections, and the listener eventually shuts itself down due to the TNS-01159 "Internal connection limit has been reached...":

 
*NOTE: The internal Listener queue is limited to 1024 so after 1023 the TNS errors will occur and the 11.2 Listener will likely shut itself down, if the queue keeps backing up.



Changes

 This may be a new installation of 11.2 on Oracle Solaris with a kernel version of 5.10 Generic_142910-17 i86pc i386 i86pc
