Hi @vas aj<mailto:vasudevan.a...@gmail.com>,
As it seems, geode fails to start JGroups channel (UDP traffic). Could you please try to start the locator with DEBUG log-level to have additional information to troubleshoot what could be happening? Also, do you have any restriction on your system regarding UDP traffic? BR, Mario. ________________________________ From: vas aj <vasudevan.a...@gmail.com> Sent: Monday, October 26, 2020 11:05 PM To: user@geode.apache.org <user@geode.apache.org> Subject: Re: Error: unable to create jgroups channel Hi all, I am starting locator using the below command gfsh> start locator --name=locator-1 --dir=/abc/pqr/ Any clue?
