Hi, I have a Ignite 2.0 cluster of 8 servers and 8 clients. It has 6 caches which are transactional and partitioned. I use pessimistic transactions with a timeout of 60 seconds. Under performance testing, I found a deadlock message in the log.
I have reviewed the code and there is no cyclic access to the caches involved in this deadlock. Any pointers to what could be causing the deadlock? Log: Caused by: javax.cache.CacheException: class org.apache.ignite.IgniteCheckedException: Deadlock detected: K1: TX1 holds lock, TX2 waits lock. K2: TX2 holds lock, TX1 waits lock.
