Re: [Hyperic-hq-discuss] Sigar - JVM crashes on s390x (not sure if JVM or Sigar bug)

[Chakresh <sig...@hy...>]

Hi Doug

Thanks for the response. 

zVM A and zVM B are running SLES9 and are 64-bit kernel servers. I compiled both 390 and s390x sigar files on SLES9 in our lab and they work fine on zVM A but on zVM B only s390 version works. When i try to run s390x sigar files, i do get the output for the version command but after that i get JVM crash. Below is the output
