so, I really don't know how to reproduce this exactly, as I'm just noticing it when debugging CSIT failures. I did pull down 80 karaf.log files from CSIT jobs and the log message complaining about "Xid cannot be reserved" and only saw it in 4 of those logs. If that's any indication, then it's not very easy to reproduce in CSIT. BUT, it's easy enough to make our CSIT show failures a couple of times a week (guessing...)
If your steps are consistent, then hopefully the root cause can be found and it'll fix it for CSIT too. JamO On 05/09/2017 08:16 PM, Josh Hershberg wrote: > Yup, that's the one.
