At 2012/06/26 13:17:18 you have the OPC server returning an error code of 0xC004000C which means you’ve got duplicate tag or group names somewhere. This seems to be causing the OPCUA server to bomb out. Not sure if this might be an actual duplicate in your tag database, or is a symptom of another issue.
The message in wrapper1 “Not enough quota is available to process this command.” is basically telling you that you’re out of memory. I’d look at making sure Ignition is configured to use the proper amount of memory by editing ignition.conf from
# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=1024to
# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=3584If that doesn’t help, I’m guessing there is a memory leak.
