Summary

0001911: cluster sessions: block 0 is reserved

Description

(rep by Ethan Larson)

We just completed the upgrade to 3.1.2 from 3.1.1, which included a
switch to clusterstore from jdbcstore as well. Things look good, except
when we shut one of the nodes down, some of the other nodes in the
cluster will sometimes throw this exception:

[11:57:01.935] java.lang.IllegalStateException: Block 0 is reserved.

Is this something to worry about? Should I file a bug? I found a
similar bug in mantis here: http://bugs.caucho.com/view.php?id=4 [^]
