Parameters of this cache are set in AtomicConfiguration (provided in IgniteConfiguration.setAtomicConfiguration). By default it's a partitioned cache with zero backups. If you didn't change this, you don't have any backups which can be the reason of the issue. Can you try to configure 1 or 2 backups or switch to REPLICATED mode and check if it works this way? -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Semaphore-blocking-on-tryAcquire-while-holding-a-cache-lock-tp3031p3088.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
