Hello,

Did you apply DST patches to your Linux distro and Java (and Oracle, if applicable), or just Linux? It certainly appears that the problem may be time-related:

hi,

thanks for your quick response. the DST was applied only to Linux and it has been rolled back now as well.

hi,
this may be related to the JIT.

can you try to export JAVA_COMPILER=NONE
before retrying the same operation?

revert.

kind regards

Hi DareDevil :)

There is a bug on 8.1.6 (fixed in 8.1.7). Is this your database version?
