This document (7008810) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 1

Situation

An IBM mainframe is running an instance of SLES 11 SP1. It has been configured to offload ssl encryption to the hardware known as the "IBM Cryptographic Accelerator" (ICA). Occasionally, processes which rely on encryption (such as ssh, sftp, and utilities related to the ICA) will hang.

Resolution

This has been corrected in packages released through Online Updates in May 2011. Minimum package versions with the fixes are:

openCryptoki 2.3.0-0.11.1

libica-2_0_2-2.0.2-0.6.3
