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!
