Error description
Customer issuing ftp command from TSO receives: Message EZA2590E / EDC5157I errno2=0x11320142 when using FTP with z/OS as FTP Client. When Using Command FTP in TSO with z/OS as FTP-Client, we can not open the Connection to the FTP target. We get following messages: EZA1554I Connecting to: xxxx.yyyy.zzzz port: 21 initIPv4Connection: selectex() failed - EDC5157I An internal error has occurred. (errno2=0x11320142) EZA2590E selectex error from initIPv4Connection - EDC5157I An internal error has occurred. (errno2=0x11320142) PE Information: Users Affected: Users at release HBB77A0/HBB77B0 with APAR OA53761 installed; affected PTFs are listed below. z/OS 2.3 UA96076 z/OS 2.2 UA96077 User Impact: APAR OA53761 addresses an intermittant problem with kernel timer queue elements. Under certain flow and timing conditions, the high half of R14 is not cleared, leading to a bad branch and the abend0C1.
Local fix
Remove the PE PTF from the system; OA53761 fixed an intermittant problem that had very low impact. Try running the ftp job from batch.
Problem summary
**************************************************************** * USERS AFFECTED: * * All users of z/OS UNIX System Services for * * HBB77A0 and HBB77B0. * **************************************************************** * PROBLEM DESCRIPTION: * * ABEND0C1 in BPXLUKW due to bad data * * in high half of 64 bit R14. * **************************************************************** * RECOMMENDATION: * **************************************************************** APAR OA53761 exposed an existing problem in BPXLUKW. The setting of the return address in R14 for a BAKR did not clear the high half of the 64 bit register. When the high half happened to be dirty, the subsequent PR casued an 0C1 ABEND due to a wild branch above the bar.
Problem conclusion
The code setting the return address for the BAKR is changed to set the 64 bit register.
