Unfortunately I just uncovered this in a log check so I dont have any further information surrounding the circumstances. java.lang.NullPointerException at com.objectdb.o.SHN.ai(SHN.java:470) at com.objectdb.o.SHN.K(SHN.java:146) at com.objectdb.o.HND.run(HND.java:133) at java.lang.Thread.run(Thread.java:595) Full log is attached. NB: This occured in version 2-2-9_07 (as this is what we currently use in prod) so may be resolved in the latest version anyway.
