I run this same application on both x86\_64 and s390x servers, but I only see this error on the s390x side for some reason.

Gotta hand it to you; you’ve tried everything I would have thought to do except I would have used ‘nm’ instead of ‘strings’ to list symbols. Does that matter? Probably not, but may be worth checking. Assuming you’re using the default IBM JRE on the other SLES boxes maybe this is just a difference in Java on s390x, though that’s not supposed to happen, especially considering what you’ve shown us. Still looking… Good luck. ---

Could you confirm the Java vendor on the x86\_64 systems is also IBM (not Sun)? Do you by chance have some sample code that you know causes this path to be taken that could be shared? Good luck. ---

I upgraded to SDK SP3, and that helped some, now I’m getting a different error. Problem: nothing provides libyaml-0-2 = 0.1.3 needed by libyaml-devel-0.1.3-0.6.16.s390x It turns out, libyaml is on OBS for x86\_64, but nothing for s390x ---

Sorry for the delay. Some alpha geek went crazy with strace and has this analysis: I ran an strace on this and found that there is a libnet.so in the /lib64 directory that was being referenced instead of the /usr/lib64/jvm/ java-1.7.0-ibm-1.7.0/jre/lib/s390x/libnet.so ... The /lib64/libnet.so does not have the NET\_Bind defined, thus the error. It can be fixed by putting /usr/lib64/jvm/java-1.7.0-ibm-1.7.0/jre/lib/ s390x in the /etc/ld.so.conf file before the /lib and /lib64 entries, then run ldconfig. Care to try and let us know? Note that modifying things in /etc/ld.so.conf\* can affect system behavior; in this case, I assume that’s desired. There are also other ways of implementing this change I believe, like setting LD\_LIBRARY\_PATH before calling Java (or at least that SHOULD work), or using LD\_PRELOAD. Also note that this appears to address your original issue, so I’m not sure how things will be now that you have an issue with libyaml. I’m hoping somehow this will help that too. Good luck. ---

Yes this fixed it. In my case, I just relinked the libraries. I would have thought them to be identical.
