DCE: insufficient memory for the Java Runtime Environment to continue

[DCIM_Support]

I am getting this error in hs_err_pid680.log. Any thoughts?

# There is insufficient memory for the Java Runtime Environment to continue.  

# Native memory allocation (nmap) failed to allocate 310378496 bytes for committing reserved memory.

 # Possible reasons: 

 #   The system is out of physical RAM or swap space

 #   In 32 bit mode, the process size limit was hit

 # 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= 

 # This output file may be truncated or incomplete.

Dear John Smith,

Under what circumstances did the above problem occur?

Did this issue occur while the Linux desktop DCE-client was running?

With respect.

That issue was found in the DCE Server logs. Not the client. I only have windows clients installed.

Dear John Smith,

Unfortunately, it's not easy to tell the root cause of the above JVM error on the DCE-server ☹️. You can, of course, point out the lack of RAM, but this is only true if your DCE-server has only 1GB of RAM (i.e., Basic DCE appliance), and the number of monitoring devices reaches up to a thousand.

Therefore, if this problem is not frequent and regular and does not involve a real lack of RAM, then I recommend simply updating your DCE-server to the latest version 7.5.0. This is a good practice, because judging by your log-file, the JVM version is old (latest version is 1.8.0_171), and updating the DCE-server you get also the latest version of JVM, which is very important for the normal operation of DCE software.

With respect.

Thanks. The server has plenty of RAM, I think it is 16 or 20GB and 5 Cores. It should be flying!
