Subject Re: Error while adding the node the baseline topology
Date Fri, 25 Oct 2019 14:24:00 GMT
Hi - The application is doing two things, one thread is writing 2kb size
events to the ignite cache as a key value and other thread is executing
ignite SQLs thru ignite jdbc connections. The throughput is anything between
25K to 40K events per second on the cache size. We are using data streamer
for writing the key value cache. The cluster has 4 nodes with 198GB ram and
48 cores.

We got a similar error again and here is the error description:

[2019-10-25 10:16:45,399][ERROR][disco-event-worker-#142][G] Blocked

Thanx and Regards,
