With async cross-site (IRAC) and max-idle:
replicatedCache:
backups:
AccA:
backup:
strategy: "ASYNC"
stateTransfer:
chunkSize: "512"
timeout: "2400000"
maxRetries: "30"
waitTime: "2000"

expiration:

maxIdle: "1200000"
The following NullPointerException is thrown:
java.lang.NullPointerException: Cannot invoke "org.infinispan.metadata.impl.IracMetadata.getVersion()" because "remoteMetadata" is null at org.infinispan.interceptors.impl.NonTxIracRemoteSiteInterceptor.validateRemoteUpdate(NonTxIracRemoteSiteInterceptor.java:153) ... org.infinispan.xsite.ClusteredCacheBackupReceiver.removeKey(ClusteredCacheBackupReceiver.java:224) at org.infinispan.xsite.commands.remote.IracPutManyRequest$Expire.execute(IracPutManyRequest.java:186) at org.infinispan.xsite.commands.remote.IracPutManyRequest.executeOperation(IracPutManyRequest.java:61) at org.infinispan.xsite.commands.remote.IracUpdateKeyRequest.invokeInLocalCache(IracUpdateKeyRequest.java:24) at org.infinispan.xsite.commands.remote.XSiteCacheRequest.invokeInLocalSite(XSiteCacheRequest.java:55)
One possible cause, the IRAC queue is being flushed when a concurrent write happens. The tombstone is removed and nullis sent with the expiration command.
Another cause may be a concurrent tombstone cleanup while the queue is flushed.
We should skip sending the expiration request when tombstone is null here:
