I have tried upgrading from Ignition 8.1.27 to 8.1.37 and when the gateway restarts, it just hangs. In the Wrapper.log, it has an error about cannot start the JVM.
I uninstalled .37 and reinstalled .27 and it starts up OK. The wrapper.log is overwritten, so I don't know the exact code, but it definitely could not start the JVM.
Can you zip and then upload your wrapper.log file(s)? Maybe the error is in an old one?
will try to upload the wrapper log here.
wrapper.zip (373.2 KB)
Looks like it had Unrecognized VM option 'Use ConcMarkSweepGC'
and so could not create the Java Virtual Machine.
Remove this from your ignition.conf file and try again.
that appears to have worked. Thanks bschroeder
Yep! Glad it worked.
