Hi, I have apache ignite cluster of 3 ignite server and more than 20 ignite thin clients (each thin client being on separate VM). These thin clients are trying to create caches at approximately the same time parallely and also starting with cache CRUD operations after that.
Looks like partition map exchange process and cache CRUD operations in parallel are causing deadlock or lock acquire failures. *What should be the strategy to handle this scenario ?* Ignite server has below errors: *Exception stack trace 1:* WARNING: Dumping the near node thread that started transaction [xidVer=GridCacheVersion [topVer=247332659, order=1635852705217, nodeOrder=1],
