High To 100% CPU Utilization By oidldapd After Applying OID 10.1.4.3 Patchset If EUS Or Other SASL Binds Used (Doc ID 825165.1)

Last updated on MARCH 08, 2017

Applies to:

Oracle Internet Directory - Version 10.1.4.3 to 10.1.4.3 [Release 10gR3]
Information in this document applies to any platform.

Symptoms

Oracle Internet Directory (OID) 10.1.4.0.1 was operating normally without problems.
OID has also been properly tuned as per <Note 458703.1> already.

Since applying Patchset 10.1.4.3, oidldapd processes consume high to 100% cpu.

The oidldapd instances that have the problem service mostly Enterprise User Security (EUS) or other SASL connections.

The OID log for the instance number in question shows only the following error:

2009/05/06:10:03:18 * ServerListener :6 * OS thread id 7 Started
2009/05/06:10:35:36 * ServerDispatcher :4 * sgslufread: Hard error on read, OS error = 131
2009/05/06:10:57:47 * ServerDispatcher :1 * sgslufread: Hard error on read, OS error = 131
2009/05/06:11:11:45 * ServerDispatcher :3 * sgslufread: Hard error on read, OS error = 131
2009/05/06:11:19:47 * ServerDispatcher :5 * sgslufread: Hard error on read, OS error = 131
2009/05/06:11:29:49 * ServerDispatcher :2 * sgslufread: Hard error on read, OS error = 131

Note: The OS error number varies by platform, i.e.:

For OID Server on HP:
2007/06/05:10:41:12 * ServerDispatcher :2 * sgslufread: Hard error on read, OS error = 232

For OID Server on Solaris:
2007/06/13:08:36:26 * ServerDispatcher :2 * sgslufread: Hard error on read, OS error = 131

For OID Server on Linux:
2008/07/01:02:41:17 * ServerDispatcher :1 * sgslufread: Hard error on read, OS error = 104

For OID Server onWindows:
2008/07/01:02:41:17 * ServerDispatcher :1 * sgslufread: Hard error on read, OS error = 10054

These OS errors (232, 131, 104, 10054) all mean: Connection reset by peer

Changes

Applied Patchset 10.1.4.3.0.
