On Nov 10 I updated to 8.5.1 from 8.5.0 (latest patch/release), now every 24hrs of uptime, the server will hang with the following message displayed on the screen (over and over):
INFO task java:21547 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
This server is running on a MS 2012 Hyper-V host, guest OS is CentOS 6.6 with Guest Services enabled & Linux Integration Services (hyperv-daemons) installed. It has 2x 1.5GHz cores and 8GB of RAM assigned to it. I've not had any issues with 8.5.0 until now.
Does anyone have suggestions for further troubleshooting this issue please?
