Issue/Introduction
After upgrading the TAS Tile to version 10.4.2, customer noticed that the Diego Database component started to increase memory usage.
Environment
TAS 10.4.2
Cause
There’s a connectivity issue between the foundation and the syslog server causing high memory usage.
Resolution
Use the Top command to check the top memory consumer.
Top consumers:
rsyslogd: 247.6 MiB (25.3%)
bbs + bosh-dns: 132.9 MiB (13.6%)
syslog-agent, forwarder-agent, etc.: 42.5 MiB (4.4%)
If rsyslogd is consuming a lot of memory, check the /var/log/syslog logs for errors. You might see something like this:
rsyslogd: cannot connect to #.#.#.#:514 (took 0.00 seconds): Connection refused [v8.2604.0 try https://www.rsyslog.com/e/2027]
If there’s a connectivity issue, the rsyslog process will have a local log backlog causing high memory usage in the top output. Check your network firewall or load balancer for any connectivity problems between the foundation and the external syslog server.
