Based on this log message, I understood, it is related to lack of memory issue, so I have changes JVM memory settings in
“\SoftwareAG103\UniversalMessaging\server\umserver\bin\Server_Common.conf” file like…

Initial Java Heap Size (in MB)

wrapper.java.initmemory=4096

Maximum Java Heap Size (in MB)

wrapper.java.maxmemory=4096

After this change also , am not able to start the UM server, it is throwing same error.

Please help me how to resolve this issue ?, where do I have to increase free memory size ?.

Thanks in advance…!

Thanks,
Varun

Hello Varun,

This log entry suggests the machine is running out of disk space; the UM will shut down automatically if the free disk space goes below 5% in order to protect itself against file corruption due to disk write failure (when the disk gets fully exhausted).
Increasing the heap won’t help here.

Hi Stefan,

Thanks for your response.

Problem has resolved, it is space issue.

Thanks,
Varun

I would suggest and recommend you contact your Infra team to have some alerting mechanism if you are running out of disk space.

Also, check the health check tool (C:\SoftwareAG103\UniversalMessaging\tools\runner) that comes with UM.

Hi,
All the nodes in the cluster must have to be at the same version and fix level. I suggest you bring all the nodes to the same level.
