William Burns commented on ISPN-6366:
-------------------------------------
Unfortunately some things don't quite add up. If you are just restarting the node I wouldn't expect it to be doing a remote put in this way. If this was state transfer it would have a different stack trace. This looks like someone was writing to the cache directly. Unless there is something I am missing [~dan.berindei]?
But the most suspicious thing is that in your configuration you don't even have eviction enabled and yet this stack trace clearly shows a cache with eviction set to be true. Maybe there is some kind of configuration mix up?

> We have 4 instances of our application that uses Infinispan in a replicated, synchronized cluster. There are multiple independent clusters running in different data centers which share the same DB so the content of the caches is the same everywhere. The instances have been running for weeks with very little activity (the internal client application that comes in via REST API to access these apps has not been brought on live yet).
> Of the 4 cluster members, 2 (app servers) use the cache for read-only, 2 (cache managers) keep the cache up to date from the DB. The app servers keep 20,000 records in the cache and the rest in a file store. The cache managers keep all records in the cache and do not use a file store. All cluster members are configured to get a copy of the cache from others in the cluster during startup.
> Without any changes, when the two tomcat containers hosting the cache mangers were recycled, they stopped coming up. The following exception is thrown in each cache manager in catalina.out.
> The key for this cache ('EdiCache') is a 39 byte string. It is made up of two left-padded strings concatenated together. The key in the exception contains '+' which should be blank instead. When I dump the caches from a cluster that is running in a different data center, I see that the key is '128738 ' not '128738+++++++++++++++++++++++++++++++++'.
> We are using version: 8.1.0.Final
> I can upload catalina.out, my application logs and Infinispan configuration files if needed.
> Any idea what is the cause of this error?
