SAS Mid Tier issue

[sathya66]

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

Thanks for this.
I think it is last point
"In case you have many contexts wars deployed on your tomcat try reduce them"
we recentrly redployed all the web apps.
Please can you suggest, how to reduce the wars on our tomact.

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.
