Hello,

With sequoia 2.10.6 I sometime have the problem that the whole cluster
"freezes" while restoring the recovery log from one controller to the
other controller via "restore log...." command.

Especially, if there were many missed transactions due to crash of one
controller, the synchronization makes the cluster so busy (= freeze)
that the application (jboss-web) crashes with the non-recoverable
exception:

15:55:00,917 INFO  [STDOUT] Caused by:
org.continuent.sequoia.common.exceptions.
driver.protocol.BackendDriverException: Timeout in begin, still waiting
for 0 pending transactions to complete

After that, it only helps to restart the whole cluster. 

The test-servers are not really high-end machines, but what can we do?

Mfg

Sebastian
