SAS Mid Tier issue

sathya66 — Wed, 28 Oct 2020 13:18:21 GMT

All,

I am getting below waring error when I check the status of the servcies. I checked the EVM agent service status individually, I am getting the same error.

"OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000003e0400000, 693633024, 0) failed; error='Cannot allocate memory' (errno=12")

I just stopped the mid-tier services and started the services

/opt/sas/config/Lev1/sas.servers status
SAS servers status:
SAS JMS Broker is UP

A Google search of "Cannot allocate memory' (errno=12)" results in an article that discusses that you have run computer out of memory.

Here are some possible solutions:

Possible solutions:

Reduce memory load on the system
Increase physical memory or swap space
Check if swap backing store is full
Use 64 bit Java on a 64 bit OS
Decrease Java heap size (-Xmx/-Xms)
Decrease number of Java threads
Decrease Java thread stack sizes (-Xss)
Set larger code cache with -XX:ReservedCodeCacheSize=
In case you have many contexts wars deployed on your tomcat try reduce them

Issue is resolved now.
duplicate insatances/processes are running on the machine.
when I grep for the SASSERVERX_1, there are multiple processes running.
I killed all the process and restarted the services and all looks good.

thanks for your help.
