![]() APAR status Closed as program error. Error description SSL Performance Degredation with IHS 1.3.19.x and 2.0.42.x during SSL handshakesLocal fix Install GSK 5.0.5.88 There are some additional installation steps. This fix causes to use an older optimized code library. This is only for PPC boxes. Older Power architecture boxes will SIGILL almost immediately. Instructions for failing back to the older optimized code library: 1. Install GSKit as per normal. 2. The post install creates a symbolic link from /usr/lib/libgsk5krsw.so -> /usr/opt/ibm/gskkm/lib/ppc/libgsk5krsw.so We need to replace it with a link to the older optimized code library cd /usr/lib rm libgsk5krsw.so ln -s libgsk5krsw.so /usr/opt/ibm/gskkm/lib/bsafev52ppc/libgsk5krsw.so If SIGILL occurs, reinstall GSK 5.0.5.88 without the above steps.Problem summary SSL Performance issue (low performance). The li bgsk5krsw.so gskit library is taking up to much CPU.Problem conclusion Problem is in IHS1.3.26 and IHS2.0.42 gskit fixed the library to not take up CPUTemporary fix Comments
