jgroups-aws issue with Keycloak 25 and jgroups-aws 2.0.1-FINAL and 3.0.0-FINAL

[swc-hannes]

Hi,

we are usually running keycloak in FARGATE via jgroups-aws. in keycloak verison 25, they removed the cache stack option as a build parameter and now when trying to deploy via ENV vars the following errors arise.

2024-06-26 16:43:06,366 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: ISPN000541: Error while trying to create a channel using the specified configuration '[TCP(bundler.max_size=64000, sock_conn_timeout=300, linger=-1, thread_pool.keep_alive_time=60000, diag.enabled=false, bind_port=7800, thread_naming_pattern=pl, non_blocking_sends=false, thread_pool.thread_dumps_threshold=10000, send_buf_size=640k, thread_pool.max_threads=200, use_virtual_threads=false, bundler_type=transfer-queue, thread_pool.min_threads=0), RED(), aws.S3_PING(region_name=aws-region, num_discovery_runs=3, bucket_name=s3bucket-name), MERGE3(max_interval=30000, min_interval=10000), FD_SOCK2(offset=50000), FD_ALL3(), VERIFY_SUSPECT2(timeout=1000), pbcast.NAKACK2(xmit_interval=200, xmit_table_num_rows=50, resend_last_seqno=true, use_mcast_xmit=false, xmit_table_msgs_per_row=1024, xmit_table_max_compaction_time=30000), UNICAST3(conn_close_timeout=5000, xmit_interval=200, xmit_table_num_rows=50, xmit_table_msgs_per_row=1024, xmit_table_max_compaction_time=30000), pbcast.STABLE(desired_avg_gossip=5000, max_bytes=1M), pbcast.GMS(join_timeout=2000, print_local_addr=false), UFC(min_threshold=0.40, max_credits=4m), MFC(min_threshold=0.40, max_credits=4m), FRAG4(frag_size=60000)]'

followed by the folloowing line:

2024-06-26 16:45:32,153 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: JGRP000001: configuration error: the following properties in TCP are not recognized: {non_blocking_sends=false}

afterwards kc stops.

Thank you for any input. KR

Which instructions did you follow? Clearly those need updating.

For updating keycloak we removed --cache-stack=ec2 from kc.sh build ... and we introduced ENV KC_CACHE=ispn and ENV KC_CACHE_STACK=ec2.

For jgroups aws we use a bundle, I tried to increase the version from 2.0.1.Final to 3.0.0.Final.

okay nevermind, i checked my old thread and saw that I branched away from the wrong branch... of course as last time, it was needed to exclude jgroups..

correct bundle:

thank you for the hint !

Thanks so much @swc-hannes for sharing your working config, I was facing the same issue. In case it helps others, I also had to exclude:

                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-api</artifactId>
                </exclusion>

To prevent a dependency collision with SLF4J.

credits to @rhusar though, as he informed me a yr ago about this issue. Thank you @agseco for pointing out slf4j either.
