Node initialization alerts
When initialization fails, Groundplex nodes might generate one of the alerts described in the following table.
Alert | Description | Resolution |
---|---|---|
Large clock skew |
The node's clock must be in sync with the cloud servers and other nodes in the Snaplex. | Configure the node's host operating system to synchronize its clock with a time server. |
Cannot bind to "..." network port ... | By default, Snaplex nodes listen on network ports in the 8080 to 8090 range. If another service has allocated those ports, the node can't start up. | Stop the other service or change the ports configured for the Snaplex. Learn more. |
Memory size is too small | The configured heap size for the Snaplex node's JVM is too small. | Update the jcc.heap.max_size property in the
global.properties file. Learn more. |
JVM max memory size is more than the physical memory | The Snaplex node's JVM heap size is more than the host machine's physical memory size which can lead to suboptimal performance. | Reduce the JVM heap size or increase the host machine's memory size. |
Maximum number of file descriptors is too low | On Linux, file descriptors are used to open files and make network connections. Not enough descriptors can cause errors while executing pipelines. | Configure the operating system and set the maximum number of file descriptors to 4096. |
Insufficient number of processors | At least two processors are required on node hosts. | Install on a machine with more than one processor. |
Local path has incorrect permissions: ... | The node needs permission to read and write files under its installation directory. | Update the permissions on the directories mentioned in the alert. |
Unable to reach Snaplex neighbor: ... | Snaplex nodes communicate periodically. This node is having trouble communicating with another. | Check the node in the message for availability. |
The current Snaplex war version is deprecated... | The installation package is for a deprecated Snaplex version. | Update to the recommended Snaplex war version listed in the alert. |
This node shares a jetty certificate with at least one other node. Nodes sharing this certificate: ['..........'] | Multiple nodes are using the same jetty certificate/key
(jcc-serverkeys.jks and jcc-serverkeys.pass ). This can
occur when copying configuration files from one JCC node to another. |
Use a unique certificate for each node. |
The org-specific CC user should be used instead of [email protected]. | An incorrect user email address exists in the jcc.properties file. | Update the email address in Snaplex configuration. |
