WORKAROUND
1) Stop FglAM service/daemon.
2) Delete the contents inside $FglAm_Home/state/default/cache
3) Change the values shown below to increase the message cache size for both upstream and downstream from 1 MB to about 10240 MB, and upstream-verified from 512 KB to 4096 MB.
The upstream/downstream max-disk-space values are tuned to impact the system as little as possible in most use cases.
Edit the file under $FglAm_Home/state/default/config/fglam.config.xml and make the following changes and save the file.
Existing:
<config:upstream max-queue-size="-1" max-disk-space="1024" max-batch-size="500" allow-runtime-change="true"/>
<config:upstream-verified max-queue-size="-1" max-disk-space="512" max-batch-size="250" allow-runtime-change="true"/>
<config:downstream max-queue-size="-1" max-disk-space="1024" max-batch-size="500" allow-runtime-change="true"/>
Change To:
<config:upstream max-queue-size="-1" max-disk-space="10240" max-batch-size="500" allow-runtime-change="true"/>
<config:upstream-verified max-queue-size="-1" max-disk-space="4096" max-batch-size="250" allow-runtime-change="true"/>
<config:downstream max-queue-size="-1" max-disk-space="10240" max-batch-size="500" allow-runtime-change="true"/>
Confirm that the change were applied properly.
4) Delete the existing deployed negotiation configuration settings inside directory:
$FglAm_Home/state/default/config/deployments
5) Restart the Agent Manager for these settings to take effect.
